1. Raspberry Pi - GPIO : Light the LED with Python
# Blinks LED connected to pin 10
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)
GPIO.setup(10,GPIO.OUT) # set GPIO Physical Pin no 10
for i in range(100): # Repeat 100 times
GPIO.output(10,True) # switch on Pin 10
print("LED on!")
time.sleep(0.1) # Wait
GPIO.output(10,False) # switch off Pin 10
print("LED off!")
time.sleep(0.1) # Wait
print("Done..")
GPIO.cleanup() # Resets GPIO port
