Script and Tests

Script: pushbutton_test

The pushbutton_test script displays whether or not the pushbutton is pressed as values of 1 and 0.  These values are often called states.  With this pushbutton circuit and script, a state of 1 indicates pressed, and 0 indicates not pressed.

• Connect your micro:bit module to your computer with its USB cable.
• In Google Chrome or Microsoft Edge browser, open the micro:bit Python Editor. 
• Set the project name field to pushbutton_test, enter the script, and click Save. 
  (See Save & Edit Scripts.)  
• Click Send to micro:bit.
  (See Flash Scripts with Python Editor.)

# pushbutton_test

from microbit import *

state = 0
display.off()
pin6.set_pull(pin6.NO_PULL)

while True:
    state = pin6.read_digital()
    print("state = ", state)
    sleep(250)

Tests

• Click the Show serial button to open the serial monitor.
