This tutorial will go over writing your first program and using the RTk.GPIO and assumes you've already followed the guide to install python and the library installed. If not follow the guide here.

Open your favourite IDE
Open your favourite IDE or just a python shell in a terminal to begin with.
from RTk import GPIO from time import sleep LED = 22 GPIO.setmode(GPIO.BCM) GPIO.setup(LED,GPIO.OUT) while True: GPIO.output(LED,1) sleep(1) GPIO.output(LED,0) sleep(1)
