-
-Learn how to convert your BBC micro:bit into a telegraph using a second BBC micro:bit as well as pin P1, P2, 3V, GND, and crocodile clips (or spring clips). The connect BBC micro:bit uses pins P1, P2, 3V, GND.
-
-## Objectives
-
-* learn how to setup the BBC micro:bit with crocodile clips
-* learn how to telegraph to another BBC micro:bit

-In this project, you will build your ornament chain between micro:bits. Project duration: 15 minutes.
-
-## Materials
-
-* micro:bit, battery holder and 2 AAA batteries
-* Crocodile clips
-
-## Steps
-
-### Step 1
-
-![](/static/mb/lessons/banana-keyboard-1.png)
-
-Using the 1st crocodile clip, connect the end of the crocodile clip onto GND pin on the micro:bit.
-
-### Step 2
-
-![](/static/mb/lessons/ornament-chain-2.png)
-
-Using the 2nd crocodile clip, connect the end of the crocodile clip onto the 3V pin on the micro:bit.
-
-### Step 3
-
-![](/static/mb/lessons/ornament-chain-3.png)
-
-Using the 3rd crocodile clip, connect the end of the crocodile clip onto pin 1 of the micro:bit.
-
-### Step 4
-
-![](/static/mb/lessons/ornament-chain-4.png)
-
-Using the 4th crocodile clip, connect the end of the crocodile clip onto pin 2 of the micro:bit.
-
-### Step 5
-
-![](/static/mb/lessons/ornament-chain-5.png)
-
-Using the 1st crocodile clip, connect the unattached end of the crocodile clip onto the GND on the 2nd micro:bit.
-
-### Step 6
-
-![](/static/mb/lessons/ornament-chain-6.png)
-
-Using the 2nd crocodile clip, connect the unattached end of the crocodile clip onto the 3V pin on the 2nd micro:bit.
-
-### Step 7
-
-![](/static/mb/lessons/ornament-chain-7.png)
-
-Using the 3rd crocodile clip, connect the unattached end of the crocodile clip onto pin 2 of the 2nd micro:bit.
-
-### Step 8
-
-![](/static/mb/lessons/ornament-chain-8.png)
-
-Using the 4th crocodile clip, connect the unattached end of the crocodile clip onto pin 1 of the 2nd micro:bit
-
-### Step 9
-

-
-![](/static/mb/lessons/ornament-chain-1.jpg)
-
-Your ornament chain is ready!
-
-### Step 10
-
-* Connect the first micro:bit to your computer using your USB cable and run the [ornament chain](/microbit/fcicvk) script on it.
-* Connect the second micro:bit to your computer using your USB cable and run the [ornament chain](/microbit/fcicvk) script on it.
-* The first person and second person take turns pressing button A to start the ornament chain game!
