Binærteller basert på Python og gpiozero

Program for testing av oppkobling:

import gpiozero as gpzero
from time import sleep

resetbutton = gpzero.Button(3)
leds = gpzero.LEDBoard(26,16,20,21)

#  test trykknappen
while True:
    if resetbutton.is_pressed:
        print("Trykknappen virker.")
        break
    else:
        print("Test ut trykknappen.")

# test led lysene
leds.on()    
sleep(3)
leds.value = (0,0,0,1)
sleep(1)
leds.value = (0,0,1,0)
sleep(1)
leds.value = (0,1,0,0)
sleep(1)
leds.value = (1,0,0,0)
sleep(1)
leds.off()

Program for binærteller:

# Eksempel på Raspberry Pi binærteller med gpiozero
# Ref: gpiozero.readthedocs.io

import gpiozero as gpzero

# Gjør klar trykknapp and bank med led-lys
resetbutton = gpzero.Button(3)
leds = gpzero.LEDBoard(26,16,20,21)
