Coding

Importing Libraries​

  1. From Imports within the Basic menu, select and drag a from microbit import * block to the code area and attach it under the # start code here block.

  2. From Imports within the Basic menu, select and drag an import radio block to the code area and attach it under from microbit import * block.

Configuring the Radio Module​

  1. From the Radio menu, select and drag a radio.on() block to the code area and attach it under the import radio block.

  2. From the Radio menu, select and drag a radio.config(group=23) block to the code area and attach it under the radio.on() block. Change the 23 to 30.

If you are working with more than one pair of micro:bits make sure the Channel value is different per pair.

Creating the While Loop​

From Loops within the Basic menu, select and drag a while True: block to the code area and attach it under the radio.config(group=30) block.

Create Incoming Variable​

WHAT IS A VARIABLE

Think of a variable as a box that stores information that can be used throughout our program. We give variables a descriptive name so we and others can understand what is going on within our program.

  1. From Variables select Create variable.... Name the variable incoming.

  2. From Variables select and drag incoming = 0 block to the code area and attach it under the radio.config(group=30) block.

  3. From Radio select and drag a radio.receive() block and attach it within the 0 of the incoming = 0 block.

Configuring Incoming Message​

  1. From Logic within Basic, select and drag an if True: block to the code area and attach it under the incoming = radio.receive() block.

  2. From Variables select and drag an incoming block to the code area and attach it within the True of the if block.

  3. From Display, select and drag a display.show("Hello") block to the code area and attach it within the if incoming: block.

  4. From Display, select and drag a Image.RABBIT block to the code area and attach it within the Hello of the display.show block. Select RABBIT and choose GHOST

Incoming message code

Configuring Outgoing Message​

  1. From Logic within Basic, select and drag an if True: block to the code area and attach it under the if incoming: block.

  2. From Accelerometer select and drag an accelerometer.was_gesture(‘shake’) block to the code area and attach it within the True of the if block.

  3. From Display select and drag a display.clear() block to the code area and attach it within the if accelerometer.was_gesture(‘shake’) block

  4. From Radio select and drag a radio.send(“Hello”) block to the code area and attach it under the display.clear() block. Change `“Hello” to "GHOST".
