# 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

# modules
# from machine import Pin
# from time import sleep

# LED = Pin(15, Pin.OUT)      # creating LED object, setting it as OUT
# BUTTON = Pin(16, Pin.IN)    # creating Push Button object, setting it as IN

# # 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 BUTTON.value() == 1:
#         LED.on()
#         sleep(0.1)
#         print("test")

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