Working with built-in push buttons

Figure 5.1 shows two built-in push buttons in Micro:bit. They are named A and B. They are connected to GPIO pins 5 and 11, respectively. The MicroPython implementation for Micro:bit comes with built-in methods to work with them. Let’s see a simple example, as follows:

from microbit import *
try:
    while True:
        if button_a.is_pressed():
            print("Button A is pressed...")
        elif button_b.is_pressed():
            print("Button B is pressed...")
        else:
            print("No Button is pressed...")
        sleep(100)
except KeyboardInterrupt...
