# microbit-chrome
Prototype chrome addon that exposes the micro:bit's serial output to webpages.
* watch the [demo video](https://vimeo.com/146207766)
# Installation
See [developer.chrome.com](https://developer.chrome.com/extensions/getstarted#unpacked)
for instructions on how to install the local version into your chrome browser.
# Requirements
* Chrome 48 or later.
# Sample page
The `demo.html` webpage goes along with the
https://github.com/Microsoft/microbit-touchdevelop/blob/master/examples/tcs34725.cpp
program. Run `http-server` from this directory, then visit
http://localhost:8080/demo.html
(keep in mind that pages served from `file://` cannot open ports).
# Building
Open a command prompt and run the following commands.
````
npm install
typings update
````

## 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!
## 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!

# 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.
8. Enter the 6 digits which the micro:bit displayed into your Android 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 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.

# Bluetooth UART Service
### ~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.
### ~
The Bluetooth UART service allows another device such as a smartphone to exchange any data it wants to with the micro:bit, in small chunks which are intended to be joined together. [UART[(https://en.wikipedia.org/wiki/Universal_asynchronous_receiver/transmitter) stands for Universal Asynchronous Receiver Transmitter and is one way in which serial data communications can be performed, usually between two devices connected by a physical, wired connection. The Bluetooth UART service emulates the behaviour of a physical UART system and allows the exchange of a maximum of 20 bytes of data at a time in either direction.
When this service is used, the micro:bit sets up a 60 byte buffer and data it receives will be accumulated in the buffer until it is full. When using the UART service from your micro:bit code, you can indicate a special character which will be used to mean that the entire message in at most three chunks has now been sent by the other, connected device, at which point the micro:bit will release the entire contents of its buffer to any code trying to read it. In other words this special character, known as a 'delimiter' is used by the device connected to the micro:bit to mean "I've sent my whole message, you can now use it".
You could use the UART service for many things. It doesn't care what you put in messages which makes it very flexible. You could create a guessing game, with questions and answers passing between micro:bit and a smartphone or you could connect a camera to the micro:bit and transmit image data obtained from the edge connector, in chunks over Bluetooth to a smartphone. There are a great many possibilities.
To use the Bluetooth UART service from another device you'll need additional micro:bit code which reads and uses data from the UART buffer and / or writes data to the buffer for transmission over Bluetooth to another device.
```sig
bluetooth.startUartService();
```
### Example: Starting the Bluetooth UART service
The following code shows the Bluetooth UART service being started:

The [Bluetooth UART service](start-uart-service.md) allows another device such as a smartphone to exchange any data it wants to with the micro:bit, in small chunks.
With the Bluetooth UART service running, this block allows a micro:bit to read data which has been received from a Bluetooth connected device, terminating reading and returning the value obtained as soon as a specified delimiter character is encountered. This means that connected devices can send data to the micro:bit and indicate that the complete message has been sent by appending the message with the delimiter character.
```sig
bluetooth.uartRead("");
```
### Example: Starting the Bluetooth UART service and then reading data received from another device which is terminated by ":" character and then displaying it
```blocks
let uart_data = "";
let connected = 0;
basic.showString("UART");
bluetooth.onBluetoothConnected(() => {
basic.showString("C");
connected = 1;
while (connected == 1) {
uart_data = bluetooth.uartRead(":");
basic.showString(uart_data);
}
});

# UART Write
### ~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.
### ~
The [Bluetooth UART service](start-uart-service.md) allows another device such as a smartphone to exchange any data it wants to with the micro:bit, in small chunks.
With the Bluetooth UART service running, this block allows a micro:bit to send data to a Bluetooth connected device.
```sig
bluetooth.uartWrite("");
```
### Example: Starting the Bluetooth UART service and then sending "HELLO" whenever button A is pressed and another device has connected over Bluetooth
```blocks
let connected = 0;
bluetooth.onBluetoothConnected(() => {
basic.showString("C");
connected = 1;
});
bluetooth.onBluetoothDisconnected(() => {
basic.showString("D");
connected = 0;
});
input.onButtonPressed(Button.A, () => {
if (connected == 1) {
bluetooth.uartWrite("HELLO");
}
});
```

# In Background
# Run In Background
Run code in the background as a separate process or thread; for more information on this advanced construct, see [the micro:bit - a reactive system](/device/reactive).

### Example
The example below shows how a background process can be used to display the current value of the global variable `num`, while code (like the `on button pressed` handler) can change the value of the variable.
This program shows how running in the background can say what is
stored in a variable like `num`, while another part (``on button pressed``)

# Reset
Reset the BBC micro:bit (as if you pushed the reset button on the back of the device), which causes the program to start again.
Reset the BBC micro:bit and start the program again.
This function is like pressing the reset button on the back of the micro:bit.
```sig
control.reset()

### Example
This program will count as high as you like when you press button `A`.
When you get tired of counting, press button `B` to reset the
micro:bit and start the program over.
```blocks
let item = 0;
basic.showNumber(item);
input.onButtonPressed(Button.A, () => {
item = item + 1;

# Set Accelerometer Range
Set up the part of the micro:bit that measures
[acceleration](/reference/input/acceleration) (how much the microbit
is speeding up or slowing down), in case you need to measure high
or low acceleration.
### Parameters
* the biggest number of gravities of acceleration you will be
measuring (either 1G, 2G, 4G, or 8G). Any bigger numbers will be
ignored by your micro:bit, both when you are picking a number of
gravities, and when you are measuring acceleration.
### Example
This program says the highest acceleration that your micro:bit
will measure is 4G. Then it measures acceleration from side to side
until you stop the program.
```blocks
input.setAccelerometerRange(AcceleratorRange.FourG);
basic.forever(() => {
basic.showNumber(input.acceleration(Dimension.X));
});
```

# Streaming
This page describes how to stream data from the micro:bit to the editor or even to the cloud.
## Before starting...
Make sure you follow the instructions on [how to setup a serial connection](/device/serial) with the micro:bit.
## A typical scenario
A common scenario is to chart some sensor data, such as the acceleration, and analyse it in the editor.
For example, run this code on your micro:bit.
```blocks
basic.forever(() => {
led.plotBarGraph(input.acceleration(Dimension.X), 0);
});
```
If your serial connection is working, you will start to see a chart representing that acceleration ``x`` value read from the micro:bit.
Each time ``led.plotBarGraph`` is called, the value is also written to the serial output. The log view automatically detects
that there is a data stream and displays a graph.
## Local download
The log view will automatically start to collect and organize the data it detects. Simply click on the log view to open the various options
to export the data. The simplest option is to download the data as a **CSV file**. This file can easily be opened in programs like Office Excel.
## Cloud upload via Azure
In the data export dialog, there is another option to upload the data to the Azure cloud. This allows to upload small amounts of data
without any kind setup. The data can be accessed via web services or directly from Office Excel.
