3. Radio temperature

3.1. Indoor and outdoor temperature

Set up the group in pairs with a value 0-255 by modifying the group in: radio.config(group=8).
Turn on the radio using: radio.on()
Use different code for the outdoor microbit compared to the indoor.
Outdoor: Set up the outdoor microbit so that it only sends the temperature every minute
from microbit import *
import radio

# Choose own group in pairs 0-255
radio.config(group=8)
# Turn on the radio
radio.on()

while True:
    outdoor_temp = temperature()
    radio.send(str(outdoor_temp))
    sleep(60000)
Indoor: Set up the indoor microbit so that pressing the A-button displays the indoor temperature and pressing the B-button displays the outdoor temperature.
from microbit import *
import radio

# Choose own group in pairs 0-255
radio.config(group=8)
# Turn on the radio
radio.on()

outdoorTemp = '-'

while True:
    incoming_message = radio.receive()
    if incoming_message:
        outdoorTemp = incoming_message
    if button_a.was_pressed():
        display.scroll(str(temperature()))
    elif button_b.was_pressed():
        display.scroll(outdoorTemp)

Tasks

  1. Modify the code of the microbits so that they both scroll the outdoor temperature every 60 seconds.

  2. Modify the code of the outdoor microbit so that when the outdoor microbit is reset along with pressing the A-button, the time between sends is 10 seconds. When it is reset along with pressing the B-button, the time between sends is 30 seconds. On reset with button pressing the sleep time is 60 seconds.

Tasks

#. See: https://pc-microbit-micropython.readthedocs.io/en/latest/introduction/power_management.html#deep-sleep-wake-via-run-every Modify the code of the outdoor microbit so that it uses deep sleep which is renewed every 24 hours, along with run_every to send the temperature every 60 seconds.
