Last summer I created some resources to use with Micro:bit/s for CPC and over the next few months and I will try and share the best bits with the kind permission of CPC.
This one uses Micropython and a neopixel again. The neopixel is from this kit:
The picture below shows how the Micro:bit is set up, This time it uses the radio module to light up an neo-pixel on another Micro:bit, after one of the buttons is pressed.
Instructions
You
will need to code the Micro:bit with MU either on a PC/ MAC or Linux machine.
At the time of writing the BBC website will not allow the radio module to work.
This program uses the radio on the
Micro:bit to send messages to trigger neo-pixels on other Micro:bits. The radio
code here is taken from the demo by N Toll on the Micro:bit read the docs
website.
You will need at least two
Micro:bits in order to see it working, both Micro:bits will need the same code
loaded onto each one.
Code to go on each Micro:bit:
from microbit import *
import neopixel
np = neopixel.NeoPixel(pin0,1)
import radio
import random
#import neopixel
#from microbit import display,
Image, button_a, sleep
#np = neopixel.NeoPixel(pin0,1)
def Angry():
np[0] = (255,0,0)#Red
np.show()
display.show(Image.ANGRY)
sleep(3000)
display.clear()
np.clear()
def Happy():
np[0] = (0,255,0)#Green
np.show()
display.show(Image.HAPPY)
sleep(3000)
display.clear()
np.clear()
def Meh():
np[0] = (255,69,0)#Yellow
np.show()
display.show(Image.MEH)
sleep(3000)
display.clear()
np.clear()
radio.on()
while True:
FeelingsList = ['Angry','Meh','Happy']
# Button A sends a "flash" message.
emo = random.choice(FeelingsList)
if button_a.was_pressed():
radio.send(emo) # a-ha
# Read any incoming messages.
incoming = radio.receive()
if incoming == 'Meh':
Meh()
elif incoming == 'Happy':
Happy()
elif incoming == 'Angry':
Angry()
