## Prior learning/place of lesson in scheme of work
|
||||
|
||||
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

|
||||
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!
