 Let's measure `acceleration (mg)` and then `send number`. `Acceleration` is measured in **milli-gravities**, so a value of -1000 is equivalent to -1g or -9.81m/s^2. We will be able to get the acceleration value (g-force), in the specified "x" dimension. `Send number` will broadcast a number data packet to other micro:bits connected via radio.
 
 ```blocks
-radio.sendNumber(input.acceleration(Dimension.X))
+radio.sendNumber(input.acceleration(Dimension.X));
 ```
 
 We want to display the acceleration forever. In order to do so, we need a `forever` loop. A forever loop will repeat code in the background forever.
 
 ```blocks
 basic.forever(() => {
-    radio.sendNumber(input.acceleration(Dimension.X))
-})
+    radio.sendNumber(input.acceleration(Dimension.X));
+});
+

 ```
 
 We want to register code to run when a packet is received over radio. We can implement this code by adding `on data received`.

-#### Algorithms
-
-* Designs solutions (algorithms) that use repetition and two-way  selection, ie if, then and else.(AL)
-* Uses diagrams to express solutions.(AB)
-*  Uses logical reasoning to predict  outputs, showing an awareness of inputs (AL)
-* Represents solutions using a structured notation (AL) (AB)

-#### Programming & Development
-
-* Creates programs that implement algorithms to achieve given goals (AL)
-*  Declares and assigns variables(AB)
-* Uses post-tested loop e.g.‘until’,and a sequence of selection statements in programs,including an if,then and else statement(AL)
-* Understands the difference between, and appropriately uses if and if, then and else statements(AL)
-* Uses a variable and relational operators within a loop to govern termination (AL) (GE)
-* Uses a range of operators and expressions e.g. Boolean, and applies them in the context of program control. (AL)
-* Selects the appropriate data types(AL) (AB

+## Objectives
+
+* learn how to get the number of milliseconds elapsed since the script began. 1,000 milliseconds = 1 second
+* learn how to create a global variable to store data so that you can use it later in your code and will be accessible across functions and in nested code blocks
+* learn how to create a Boolean with one of two possible values: true or false
+* learn how to run code when an input button is pressed
+* learn how to conditionally run code depending on whether a condition is true or not
+* learn how to show a string on the LED screen one character at a time

+
+Have you ever tried to communicate through a telegraph? Let's try coding a "Telegraph" on two BBC micro:bits !
+
+
+Complete the following [guided tutorial](/microbit/lessons/telegraph/activity), your hack should look like this:
+
+![](/static/mb/lessons/telegraph-0.png)
+
+### Step 1
+
+We now need to digitally write to the specified pin (P0) as digital. Let's start by adding the code in the pin drawer that includes 'digital write (0,1) to pin P0'.. Then insert 1 for digital write. 
+
+```blocks
+pins.digitalWritePin(DigitalPin.P0, 1)
+
+```
+
+### Step 2
+
+We want to add a block to turn on an LED in the middle area of the LED display using plot x, y. So insert the appropriate LED plot x, y. 
+
+```blocks
+pins.digitalWritePin(DigitalPin.P0, 1)
+led.plot(2, 2)
+
+```
+
+### Step 3
+
+We want to insert a condition that tells us when to turn on the LED. So insert the if block under logic drawer. Then add a condition that occurs if we do not turn on a LED with plot x, y. We also should plot an LED on the display if button A is pressed. Your code should appear as follows:
+
+```blocks
+if (input.buttonIsPressed(Button.A)) {
+    pins.digitalWritePin(DigitalPin.P0, 1)
+    led.plot(2, 2)
+} else {
+
+}
+```
+
+
+### Step 4
+
+We want to write code if button A is NOT pressed. It is important to say that digital write is not on. We also want to turn off all LED lights on the LED screen
+
+```blocks
+if (input.buttonIsPressed(Button.A)) {
+    pins.digitalWritePin(DigitalPin.P0, 1)
+    led.plot(2, 2)
+} else {
+    pins.digitalWritePin(DigitalPin.P0, 0)
+    basic.clearScreen()
+}
+```
+
+### Step 5
+
+Let's add a forever loop so this code runs in the background forever. Modify your code so that your code looks like this. Run the code and press Button A. 
+
+```blocks
+basic.forever(() => {
+    if (input.buttonIsPressed(Button.A)) {
+    pins.digitalWritePin(DigitalPin.P0, 1)
+    led.plot(2, 2)
+} else {
+    pins.digitalWritePin(DigitalPin.P0, 0)
+    basic.clearScreen()
+}    
+})
+
+```
+
+### Step 6
+
+
+We now need to digitally read to the specified pin (P1) as digital. Let's start by going to the pin drawer and adding digital read pin (0,1) and changing the pin to P1. Now we need to create a condition for digital read pin (0,1). So we go to the logic drawer and select the comparison operator. Then we want to set the comparison operator to 1 to turn on digital read on pin 1. We want to insert a condition that tells us if button A is pressed and we should turn on digital read on pin 1. So insert the if block under logic drawer. Then add a condition that occurs if digital read on P1 is on. Then we want to plot x, y at the x, y coordinates of 2,2. we also want to say that if digital read pin P1 is not on, we want to turn off all LED lights on the screen. Your code should appear as follows:
+
+```blocks
+if (pins.digitalReadPin(DigitalPin.P1) == 1) {
+    led.plot(2, 2);
+}
+else {
+    basic.clearScreen();
+}
+basic.forever(() => {
+    if (input.buttonIsPressed(Button.A)) {
+        pins.digitalWritePin(DigitalPin.P0, 1);
+        led.plot(2, 2);
+    }
+    else {
+        pins.digitalWritePin(DigitalPin.P0, 0);
+        basic.clearScreen();
+    }
+});
+
+
+
+```
+
+Your telegraph is ready!
+
+### Step 7
+
+* Connect the first micro:bit to your computer using your USB cable and run the [telegraph](/microbit/nnudbr) script on it.
+* Connect the second micro:bit to your computer using your USB cable and run the [telegraph](/microbit/nnudbr) script on it.
+* The first person and second person take turns pressing button A to play the telegraph game!
