+control images with variables. 
+
+## Before we get started
+
+Control images with variables. 
+
+Have you ever tried to making beat box sounds? Let's try making a beatbox with code!
+
+We will register an event handler on the fruit that will execute when two things occur: first, the alligator clip attaches to GND and the other side of the alligator clip is inserted into a banana. Let's start by adding a variable where you can store data. Then rename the variable to "sound". Then set the value of the variable to the note block `A` from the Music drawer. Modify your code so that your code looks like this.
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+```
+
+We want to play music on pin pressed in order to register an event handler that will execute whenever when you run a script and click pin 1 on the simulator. We must start by opening the Input drawer and adding `on pin pressed` P1. Modify your code so that your code looks like this.
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+input.onPinPressed(TouchPin.P1, () => {
+
+})
+```
+
+We want to code the notes that will be played `on pin pressed`. We click on the Input drawer then insert a `for loop` that will increment by *i*. Click on the Variables drawer. Add `set item` block. Rename the variable block to "sound." Then add a Maths block to increase the variable sound from the note frequency of block `A` to `A` plus 25.Modify your code so that your code looks like this
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+input.onPinPressed(TouchPin.P1, () => {
+    for (let i = 0; i < 4; i++) {
+        sound = sound + 25
+    }
+})
+```
+
+
+* click *run* to see if the code works as expected.
+
+
+
+Let's include a second sound `on pin pressed` *P2*. To do this, you need to add the same blocks as the banana keyboard activity. However, you must change alter `on pin pressed` from P1 to P2. Additionally, you must *decrease* the frequency of the variable "sound" by 25. Modify your code so that your code looks like this. You will need to include a second banana to a alligator (spring) clip in the same procedure as the first activity. 
+
+```blocks
+let sound = music.noteFrequency(Note.A);
+
+input.onPinPressed(TouchPin.P1, () => {
+    for (let i = 0; i < 4; i++) {
+        sound = sound + 25
+    }
+})
+
+input.onPinPressed(TouchPin.P2, () => {
+    for (let i = 0; i < 4; i++) {
+        sound = sound - 25
+    }
+})
+```
+
+* click *run* to see if the code works as expected.

+
+Build a telgraph.
+
+# micro:bit telegraph
+
+
+
+
+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](/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](/nnudbr) script on it.
+* Connect the second micro:bit to your computer using your USB cable and run the [telegraph](/nnudbr) script on it.
+* The first person and second person take turns pressing button A to play the telegraph game!
