4. Radio tilt

4.1. Choose response by tilting

Set up the group in pairs with a value 0-255.

Use button_a.was_pressed() to send a message, T or F, based on tilting left or right.

Scroll any received messages.

from microbit import *
import radio

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

while True:
    # sender
    x_reading = accelerometer.get_x()
    if x_reading < -200:
        response = "T"
    elif x_reading > 200:
        response = "F"
    else:
        response = "-"
    display.show(response)
    if button_a.was_pressed():
        radio.send(response)
    # receiver
    incoming_message = radio.receive()
    if incoming_message:
        display.scroll(incoming_message)
        sleep(1000)

Tasks

1. Modify the code to send “Y” or “N” from tilting and button pressing so it can be used to response Yes or No questions.

2. Modify the code to send “Y” or “N” from tilting and button pressing and then show the Image.YES if “Y” is received, and the Image.NO if “N” is received.

Q1

Modify the code to send “Y” or “N” from tilting and button pressing so it can be used to response Yes or No questions.

from microbit import *
import radio

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

while True:
    # send
    x_reading = accelerometer.get_x()
    if x_reading < -200:
        response = "Y"
    elif x_reading > 200:
        response = "N"
    else:
        response = "-"
    display.show(response)
    if button_a.was_pressed():
        radio.send(response)
        sleep(100)
    # receive
    incoming_message = radio.receive()
    if incoming_message:
        display.scroll(incoming_message)
        sleep(1000)

Q2

Modify the code to send “Y” or “N” from tilting and button pressing and then show the Image.YES if “Y” is received, and the Image.NO if “N” is received.

from microbit import *
import radio

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

    while True:
        # send
        x_reading = accelerometer.get_x()
        if x_reading < -200:
            response = "Y"
        elif x_reading > 200:
            response = "N"
        else:
            response = "-"
        display.show(response)
        if button_a.was_pressed():
            radio.send(response)
            sleep(100)
        # receive
        incoming_message = radio.receive()
        if incoming_message:
            if incoming_message == "Y":
                display.show(Image.YES)
            elif incoming_message == "N":
                display.show(Image.NO)
            sleep(1000)
