# Project objective: Light up an external LED when a push button is pressed
#
# Hardware and connections used:
#   Push button to GPIO Pin 16
#   10000 ohm pull-down resistor for the push button
#   LED to GPIO Pin 15
#   220 ohm resistor for LED
# 
# Programmer: Adrian Josele G. Quional

# continuously read the signal from the push button while the board has power
while True:
    # if the signal from the button is HIGH (button is pressed), turn LED on
    if BUTTON2.value() == 2:

        print(counter)
#        LED.on()
#        sleep(0.1)

    # otherwise, turn the LED off
#    else:
#        LED.off()
