Coding

Importing Python Libraries

Below from microbit import * type import radio. This will add the radio library so we can use it within our code.

Configure the Radio Module

Type the following code below import radio. This will turn the radio module on and set the radio group.

radio.on()
radio.config(group=30)

USING MORE THAN TWO MICRO:BITS

If you are using more than two micro:bits make sure each pair is set to a different radio group

Creating the while True Loop

Type the following line of code under radio.config(group=30)

while True:

Once you press enter your cursor will automatically indent. Start typing the rest of your code from here.

Creating 'Incoming' Variable

Within the while loop create the incoming variable and set it to radio.receive(). By typing the following code.

incoming = radio.receive()

Creating the Incoming Message

Show a ghost on the display if message is incoming.

if incoming:
    display.show(Image.GHOST)

Creating Outgoing Message

NOTE

Make sure the cursor is back in line with the if statement.

We are now going to clear the micro:bit display and send the message GHOST if the micro:bit detected a 'shake'.

if accelerometer.was_gesture('shake'):
    display.clear()
    radio.send("GHOST")

Completed Code

# Imports go at the top
from microbit import *
import radio

radio.on()
radio.config(group=30)

while True:
  incoming = radio.receive()
  if incoming:
    display.show(Image.GHOST)
  if accelerometer.was_gesture('shake'):
    display.clear()
    radio.send("GHOST")

Well done you have now completed the code for Spooky Signals. Let's move on to learn how to download it to the micro:bit.
