+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

-### ~hint
-
-The ``pick random true or false`` block randomly tells the ``if``

-});
-```
-
-These blocks mean that if you press button `A`, you will add `1` to
-your score, and if you press `A` and `B` together, the micro:bit will
-show your score.
-
-When you're done, your coin flipping program should look like this:

-## Let's play Rock Paper Scissors!
-
-### ~avatar avatar
-
-Build a Rock Paper Scissors game with the BBC micro:bit!  You can play
-the game with a friend who has it on a micro:bit.  You can also play
-it with friends who are just using their hands.  (The game is built
-like a coin flipper, but with three choices instead of two.)
-
-### ~
-
-## Step 1: Getting started
-
-We want the micro:bit to choose rock, paper, or scissors when you
-shake it.  Try creating an ``on shake`` block so when you shake the
-micro:bit, it will run part of a program.
-
-Clear up the blocks and add the blocks below.
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    
-})
-```
-
-Next, when you shake the micro:bit, it should pick a random number from `0` to `2`
-and store it in the variable `item`.
-
-Add a ``set`` block with a variable. Then add a ``pick random`` block,
-and store the random number in the variable,
-like this:
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    let item = Math.random(3)
-})
-
-```
-
-### ~hint
-No one can predict random numbers. That's what makes them great for Rock Paper Scissors!
-### ~
-
-Each possible number these blocks can make (`0`, `1`, or `2`) means a different picture.
-We will show the right picture for that number on the LED screen.
-
-
-## Step 2: Picking paper
-
-Put an ``if`` block after the ``let`` block that checks whether
-`item` is `0`. Make sure the ``if`` block has an ``else if`` part
-and an ``else`` part.
-
-Next, add a ``show leds`` block that shows a
-picture of a piece of paper:
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    let item = Math.random(3)
-    if (item == 0) {
-        basic.showLeds(`
-            # # # # #
-            # . . . #
-            # . . . #
-            # . . . #
-            # # # # #
-            `)
-    } else if (false) {
-
-    } else {
-
-    }
-})
-```
-
-## Step 3: A random rock
-
-Now we are going to add a new picture for the micro:bit to show
-when another random number comes up.
-
-Make the ``else if`` part check if the variable `item` is `1`.
-Then add a ``show leds`` block with a picture of a rock.
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    let item = Math.random(3)
-    if (item == 0) {
-        basic.showLeds(`
-            # # # # #
-            # . . . #
-            # . . . #
-            # . . . #
-            # # # # #
-            `)
-    } else if (item == 1) {
-        basic.showLeds(`
-            . . . . .
-            . # # # .
-            . # # # .
-            . # # # .
-            . . . . .
-            `)
-    } else {
-
-    }
-})
-```
-
-## Step 4: Suddenly scissors
-
-Add a ``show leds`` block with a picture of scissors to the ``else`` part:
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    let item = Math.random(3)
-    if (item == 0) {
-        basic.showLeds(`
-            # # # # #
-            # . . . #
-            # . . . #
-            # . . . #
-            # # # # #
-            `)
-
-    } else if (item == 1) {
-        basic.showLeds(`
-            . . . . .
-            . # # # .
-            . # # # .
-            . # # # .
-            . . . . .
-            `)
-    } else {
-        basic.showLeds(`
-            # # . . #
-            # # . # .
-            . . # . .
-            # # . # .
-            # # . . #
-            `)
-    }
-})
-
-```
-
-### ~hint
-
-You don't need to check if `item` is `2` because `2` is the only number left out of `0`, `1`, and `2`.
-That's why you can use an ``else`` instead of an ``else if``.
-
-### ~
-
-Your game is ready!
-
-Click **Compile** to move your program to the BBC micro:bit!
-
-Have fun!
-
-## Step 5: Are you the greatest?
-
-Here is a way you can make your Rock Paper Scissors game better.
-When button ``A`` is pressed, 
-the micro:bit will add `1` to your score.
-
-Open the ``Game`` drawer, and then add the block ``change score by 1`` to your program,
-like this:
-
-```blocks
-input.onButtonPressed(Button.A, () => {
-    game.addScore(1)
-})
-
-```
-
-## Step 6: Prove you're the greatest!
-
-After your micro:bit can add `1` to the score, show how many wins you have.
-
-```blocks
-input.onButtonPressed(Button.A, () => {
-    game.addScore(1)
-    basic.showString("WINS:")
-    basic.showNumber(game.score())
-})
-```
-## Step 7: Staying honest
-
-Success! Your micro:bit can track wins!
-But what about losses? 
-Use the ``Game`` drawer to subtract `1` from your score when you press button `B`. 
-
-Here are all the blocks you will need:
-
-```shuffle
-input.onButtonPressed(Button.B, () => {
-    game.addScore(-1)
-    basic.showString("LOSSES:")
-    basic.showNumber(game.score())
-})
-```
-Click **Compile** to move your program to the BBC micro:bit!

+
+You can also use the pins as buttons.  (The pins are the holes in the
+metal stripe at the bottom of the micro:bit board.)  For example, hold
+the ``GND`` button with one hand and touch the ``0`` pin (called
+``P0``) with your other hand to tell the micro:bit you're pressing it.
+
+Unscramble the blocks in the editor to show a heart when you touch
+pin ``P0``.
+
+```shuffle
+input.onPinPressed(TouchPin.P0, () => {
+    basic.showLeds(`
+. # . # .
+# . # . #
+# . . . #
+. # . # .
+. . # . .`);
+});
+```
+Click **Compile** to move your program to the BBC micro:bit!
+
+## ~hint
+
+Try this experiment: find a friend and hold hands. Touch the ``GND``
+pin while your friend presses the ``P0`` pin. You should see the
+heart! The electric current is going through your bodies and across
+your handshake to make it happen!

+# The amazing coin flipper
+
+### ~avatar avatar
+
+Are you trying to choose whether to play soccer or go to the movies
+instead, or which toppings to have on your pizza?  Build a coin
+flipping machine with the BBC micro:bit to choose for you!
+
+### ~
+
+Here are the blocks to make your coin flipper.  When you press button
+`B`, the coin flipper will show either `H` for heads or `T` for tails
+on the LED screen.
+
+```blocks
+input.onButtonPressed(Button.B, () => {
+    if (Math.randomBoolean()) {
+        basic.showString("H");
+    } else {
+        basic.showString("T");
+    }
+});
+```
+### ~hint
+
+The ``pick random true or false`` block randomly tells the ``if``
+block `true` or `false`.  If the ``pick`` block picked `true`, the
+``if`` block shows the letter `H`. Otherwise, it shows the letter `T`.
+
+That's it!
+
+### ~
+
+### Keeping score
+
+#### ~avatar
+
+To keep track out of how many guesses you've won,
+add these blocks to your coin flipper:
+
+#### ~
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1);
+});
+input.onButtonPressed(Button.AB, () => {
+    basic.showNumber(game.score());
+});
+```
+
+These blocks mean that if you press button `A`, you will add `1` to
+your score, and if you press `A` and `B` together, the micro:bit will
+show your score.
+
+When you're done, your coin flipping program should look like this:
+
+```blocks
+input.onButtonPressed(Button.B, () => {
+    if (Math.randomBoolean()) {
+        basic.showString("H");
+    } else {
+        basic.showString("T");
+    }
+});
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1);
+});
+input.onButtonPressed(Button.AB, () => {
+    basic.showNumber(game.score());
+});
+```

+Flip until your thumbs get tired!

+# Rock Paper Scissors
+
+### ~avatar avatar
+
+Build a Rock Paper Scissors game with the BBC micro:bit!  You can play
+the game with a friend who has it on a micro:bit.  You can also play
+it with friends who are just using their hands.  (The game is built
+like a coin flipper, but with three choices instead of two.)
+
+### ~
+
+## Step 1: Getting started
+
+We want the micro:bit to choose rock, paper, or scissors when you
+shake it.  Try creating an ``on shake`` block so when you shake the
+micro:bit, it will run part of a program.
+
+Clear up the blocks and add the blocks below.
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    
+})
+```
+
+Next, when you shake the micro:bit, it should pick a random number from `0` to `2`
+and store it in the variable `item`.
+
+Add a ``set`` block with a variable. Then add a ``pick random`` block,
+and store the random number in the variable,
+like this:
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let item = Math.random(3)
+})
+
+```
+
+### ~hint
+No one can predict random numbers. That's what makes them great for Rock Paper Scissors!
+### ~
+
+Each possible number these blocks can make (`0`, `1`, or `2`) means a different picture.
+We will show the right picture for that number on the LED screen.
+
+
+## Step 2: Picking paper
+
+Put an ``if`` block after the ``let`` block that checks whether
+`item` is `0`. Make sure the ``if`` block has an ``else if`` part
+and an ``else`` part.
+
+Next, add a ``show leds`` block that shows a
+picture of a piece of paper:
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let item = Math.random(3)
+    if (item == 0) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+    } else if (false) {
+
+    } else {
+
+    }
+})
+```
+
+## Step 3: A random rock
+
+Now we are going to add a new picture for the micro:bit to show
+when another random number comes up.
+
+Make the ``else if`` part check if the variable `item` is `1`.
+Then add a ``show leds`` block with a picture of a rock.
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let item = Math.random(3)
+    if (item == 0) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+    } else if (item == 1) {
+        basic.showLeds(`
+            . . . . .
+            . # # # .
+            . # # # .
+            . # # # .
+            . . . . .
+            `)
+    } else {
+
+    }
+})
+```
+
+## Step 4: Suddenly scissors
+
+Add a ``show leds`` block with a picture of scissors to the ``else`` part:
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let item = Math.random(3)
+    if (item == 0) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+
+    } else if (item == 1) {
+        basic.showLeds(`
+            . . . . .
+            . # # # .
+            . # # # .
+            . # # # .
+            . . . . .
+            `)
+    } else {
+        basic.showLeds(`
+            # # . . #
+            # # . # .
+            . . # . .
+            # # . # .
+            # # . . #
+            `)
+    }
+})
+
+```
+
+### ~hint
+
+You don't need to check if `item` is `2` because `2` is the only number left out of `0`, `1`, and `2`.
+That's why you can use an ``else`` instead of an ``else if``.
+
+### ~
+
+Your game is ready!
+
+Click **Compile** to move your program to the BBC micro:bit!
+
+Have fun!
+
+## Step 5: Are you the greatest?
+
+Here is a way you can make your Rock Paper Scissors game better.
+When button ``A`` is pressed, 
+the micro:bit will add `1` to your score.
+
+Open the ``Game`` drawer, and then add the block ``change score by 1`` to your program,
+like this:
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1)
+})
+
+```
+
+## Step 6: Prove you're the greatest!
+
+After your micro:bit can add `1` to the score, show how many wins you have.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1)
+    basic.showString("WINS:")
+    basic.showNumber(game.score())
+})
+```
+## Step 7: Staying honest
+
+Success! Your micro:bit can track wins!
+But what about losses? 
+Use the ``Game`` drawer to subtract `1` from your score when you press button `B`. 
+
+Here are all the blocks you will need:
+
+```shuffle
+input.onButtonPressed(Button.B, () => {
+    game.addScore(-1)
+    basic.showString("LOSSES:")
+    basic.showNumber(game.score())
+})
+```
+Click **Compile** to move your program to the BBC micro:bit!

+# JavaScript
+
+You can write micro:bit programs in a subset of [TypeScript](https://www.typescriptlang.org), a superset of JavaScript.
+Many micro:bit programs, especially at the beginner's level, are just plain JavaScript. TypeScript introduces class-based 
+object-oriented programming, such as:
+
+```typescript
+class Greeter {
+    greeting: string;
+    constructor(message: string) {
+        this.greeting = message;
+    }
+    greet() {
+        return "Hello, " + this.greeting;
+    }
+}
+
+let greeter = new Greeter("world");
+basic.showString(greeter.greet())
+```
+
+This site is meant for teaching programming first, and JavaScript second. For this
+reason, we have stayed away from concepts that are specific to JavaScript (for
+example, prototype inheritance), and instead focused on ones common to most
+modern programming languages (for example, loops, lexically scoped variables,
+functions, classes, lambdas).
+
+We leverage TypeScript's [type inference](http://www.typescriptlang.org/docs/handbook/type-inference.html) so that
+students need not specify types when clear from context.
+
+## Supported language features
+
+* top-level code in the file: "Hello world!" really is just `basic.showString("Hello world!")`
+* [basic types](http://www.typescriptlang.org/docs/handbook/basic-types.html)
+* [variable declarations](http://www.typescriptlang.org/docs/handbook/variable-declarations.html): `let`, `const`, and `var`
+* [functions](http://www.typescriptlang.org/docs/handbook/functions.html) with lexical scoping and recursion
+
+### User-defined types and modules
+
+* [classes](http://www.typescriptlang.org/docs/handbook/classes.html) with fields, methods and constructors; `new` keyword
+* [enums](http://www.typescriptlang.org/docs/handbook/enums.html)
+* [namespaces](http://www.typescriptlang.org/docs/handbook/namespaces.html)  (a form of modules) 
+
+### Control-flow constructs
+
+* `if ... else if ... else` statements
+* `while` and `do ... while` loops
+* `for(;;)` loops (see below about `for ... in/of`)
+* `break/continue`; also with labeled loops
+* `switch` statement (on numbers only)
+* `debugger` statement for breakpoints
+
+### Expressions
+
+* conditional operator `? :`; lazy boolean operators
+* all arithmetic operators (including bitwise operators); note that in microcontroller targets
+  all arithmetic is performed on integers, also when simulating in the browser
+* strings (with a few common methods)
+* [string templates](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) (`` `x is ${x}` ``)
+* arrow functions `() => ...`
+* array literals `[1, 2, 3]`
+
+
+## Unsupported language features
+
+We generally stay away from the more dynamic parts of JavaScript. 
+Things you may miss and we may implement:
+
+* exceptions (`throw`, `try ... catch`, `try ... finally`)
+* `for ... of` statements
+* object literals `{ foo: 1, bar: "two" }`
+* method-like properties (get/set accessors)
+* class inheritance

-Coding challenges for the offset image tutorial.
-
-## Before we get started
-
-Complete the following exercise. Your code should look like this:
-
-```blocks
-offset = 0
-basic.forever(() => {
-    if (offset == -4) {
-        basic.showString("Push button A", 150)
-    }
-    images.createImage(`
-. . # . .
-. . # . .

-. . # . .
-`).showImage(offset)
-})
-input.onButtonPressed(Button.A, () => {
-    offset = offset + 1
-})
-```
-
-### Challenge 1
-
-Create a condition for if button `B` is pressed. We want the image to move to the left when button `B` is pressed.
-
-```
-offset = 0
-basic.forever(() => {
-    if (offset == -4) {
-        basic.showString("Push button A", 150)
-    }

-}) // ***
-```
-
-* Run the code to see if it works as expected.
-
-### Challenge 2
-
-
-
-Now we want to make sure that the button does not go off the screen to the right. Add a new line that checks to see if offset = 5 after button `A` is pressed.
-
-If `offset = 5` then prompt the user to move the image to the left by displaying the text: "Push button B".
-
-```

+# Bluetooth Pairing 
+
+### ~hint
+![](/static/bluetooth/Bluetooth_SIG.png)
+
+For another device like a smartphone to use any of the Bluetooth "services" which the micro:bit has, it must first be [paired with the micro:bit](/reference/bluetooth/bluetooth-pairing). Once paired, the other device may connect to the micro:bit and exchange data relating to many of the micro:bit's features.
+
+### ~
+
+### What is 'pairing'?
+
+'Pairing' is what you have to do to have your micro:bit trust another device like a smartphone and similarly, have your smartphone trust your micro:bit. Why 'trust'? Well, pairing is all about security. You wouldn't usually want just anyone's smartphone connecting to your micro:bit and making it do things so by pairing *your* smartphone with *your* micro:bit you ensure that only your devices can talk to each other.     
+
+Once you've paired your micro:bit with another device it also means that they are able to exchange information privately, without someone else being able to "see" the data they're exchanging over the air using Bluetooth. This is accomplished by data being [encrypted](https://en.wikipedia.org/wiki/Encryption) and pairing makes it possible for devices who trust each other to encrypt and decrypt data from each other.
+
+# How do you pair your micro:bit with another device?
+
+Making your micro:bit pair requires you to follow some simple steps which will be described shortly. What you do with the device you're pairing it to will vary slightly depending on what that device is. We'll look at how it's done with common smartphones and tablets here too.
+
+To get your micro:bit ready for pairing do the following:
+
+1. Hold down buttons A and B on the front of your micro:bit together. The front is the side with two buttons and the LED display. Keep the two buttons held down. Don't let go of them yet!
+2. While still holding down buttons A and B, press and then release the reset button on the back of the micro:bit. Keep holding down buttons A and B.
+3. You should see "PAIRING MODE!" start to scroll across the micro:bit display. When you see this message start to appear you can release buttons A and B.
+4. Eventually you'll see a strange pattern on your micro:bit display. This is like your micro:bit's signature. Other people's micro:bits will probably display a different pattern.
+
+Your micro:bit is now ready to be paired with the other device. Read the section below which relates to your 'other' device and watch the video too. 
+
+### How do you pair your micro:bit with a Windows smartphone or tablet?
+
+1. Go into Settings
+2. Select Bluetooth
+3. Switch your micro:bit into 'pairing mode' using the steps above
+4. Wait until 'PAIRING MODE!' has finished scrolling across the micro:bit display. You should see your micro:bit listed on your Windows smartphone with a name something like 'BBC micro:bit [zatig]'. Note that the 5 characters in brackets at the end will vary.
+5. On the Windows smartphone, tap the micro:bit named in the device list. This will initiate the pairing process.
+6. The micro:bit will display a left pointing arrow and the Windows smartphone will pop up a box into which you will be invited to enter a "pin" (Personal Identity Number).
+7. Press button A on the micro:bit and watch carefully as the micro:bit displays a sequence of 6 random numbers. You may find it easier to write them down than to remember them.
+8. Enter the 6 digits which the micro:bit displayed into your Windows smartphone in the pop-up box provided and then select "done".
+9. If you entered the right number the micro:bit will display a tick / check mark. If you made a mistake it will display a cross or X and you should repeat the process to try again.

+
+### How do you pair your micro:bit with an Android smartphone or tablet?
+
+1. Go into Settings
+2. Select Bluetooth
+3. Switch your micro:bit into 'pairing mode' using the steps above
+4. Wait until 'PAIRING MODE!' has finished scrolling across the micro:bit display. You should see your micro:bit listed on your Android smartphone under the heading "Available devices" with a name something like 'BBC micro:bit [zatig]'. Note that the 5 characters in brackets at the end will vary.
+5. On the Android smartphone, tap the micro:bit named in the Available devices list. This will initiate the pairing process.
+6. The micro:bit will display a left pointing arrow and the Android smartphone will pop up a box into which you will be invited to enter a "pin" (Personal Identity Number).
+7. Press button A on the micro:bit and watch carefully as the micro:bit displays a sequence of 6 random numbers. You may find it easier to write them down than to remember them.

+
+### How do you pair your micro:bit with an Apple iOS smartphone or tablet?
+
+The steps to pair with an Apple iOS device are different to those followed for an Android or Windows device. To trigger pairing you need an application which will try to interact with your micro:bit and it's that interaction that triggers the iOS pairing process. There are many you could use but for the purposes of this documentation we'll suggest you install the "nRF Master Control Panel" (nRF MCP) application from Nordic Semiconductor. You'll find it in the Apple app store. It's a really useful Bluetooth application which will help you learn about Bluetooth as well as it having the ability to trigger the pairing process. After installing nRF MCP you should follow these steps to pair with your micro:bit:
+
+1. Switch your micro:bit into 'pairing mode' using the steps above
+2. Wait until 'PAIRING MODE!' has finished scrolling across the micro:bit display.
+3. Launch the nRF MCP application. Your micro:bit should be listed and have a "Connect" button next to it.
+4. Select "Connect" to connect your Apple device to the micro:bit. This will trigger the pairing process.
+5. The micro:bit will display a left pointing arrow and the Apple device will pop up a box into which you will be invited to enter a "pin" (Personal Identity Number).
+6. Press button A on the micro:bit and watch carefully as the micro:bit displays a sequence of 6 random numbers. You may find it easier to write them down than to remember them.
+7. Enter the 6 digits which the micro:bit displayed into your Apple device in the pop-up box provided and then select "Pair".
+8. If you entered the right number the micro:bit will display a tick / check mark. If you made a mistake it will display a cross or X and you should repeat the process to try again.

+
+
+### How often do I need to pair my micro:bit with my phone?
+
+You do *not* need to pair your micro:bit and smartphone or tablet every time you use them together. Pairing establishes 'trust' which will be retained until it is somehow lost. When another device wants to talk to your micro:bit it must connect to it but connecting and pairing are not the same thing.
+
+There are circumstances which will result in pairing data being lost however and when this happens you will need to pair again.  
+
+Currently, flashing new code via a USB cable causes the micro:bit's Bluetooth pairing data to be lost. Consequently, if you do flash new code to your micro:bit using a USB cable you will need to pair again.
+
+In contrast if you upload new code to your micro:bit over Bluetooth, using for example the Samsung micro:bit application for Android devices, you will not need to pair again.
+
+If you do find yourself needing to pair again you will first need to remove the pairing from your other device (i.e. smartphone or tablet):
+
+* On Android go into Settings/Bluetooth, select the 'cog' next to your micro:bit and then select FORGET
+* On iOS go into Settings/Bluetooth, select your micro:bit and then select Forget This Device
+* On a Windows device go into Settings/Bluetooth. Press and hold the micro:bit entry on the Windows device. A pop-up will appear with the option "delete". Select "delete" to unpair your micro:bit.

+
+### ~
+
+The Bluetooth accelerometer service allows another device such as a smartphone to wirelessly receive data from the micro:bit's accelerometer. An accelerometer detects motion. More precisely, it measures acceleration in one or more of three directions which we call X, Y and Z. 
+
+Using the Bluetooth accelerometer service you could, for example, create a smartphone application which makes a loud noise whenever your micro:bit (or the important thing you've attached it to) is moved. Or you could use your micro:bit to control the movement of a cartoon character in a game on your smartphone just by tilting the micro:bit in the direction you want the character to move in.     
+
+No additional code is needed on the micro:bit to use the Bluetooth accelerometer service from another device.

+
+### ~
+
+The Bluetooth button service makes it possible for another device such as a smartphone to be notified wirelessly whenever a button on the front of a micro:bit is pressed. Each of the two micro:bit buttons can be in one of three possible states:
+
+* Not pressed
+* Pressed
+* Long press - pressed and held down for at least 2 seconds  
+
+The button service allows you to make other things which are connected to your micro:bit using Bluetooth respond in some way when you press either of the buttons. You could, for example, hide your smartphone somewhere in the room and have it make an amusing noise when you press either of the buttons on your micro:bit. We'll leave it to you to decide what would be amusing.
