安裝GPIO Lib並測試：

 

$ sudo apt-get install RPi.GPIO

#!/usr/bin/env python
import time
import RPi.GPIO as GPIO
LED_PIN = 12
print(GPIO.VERSION)
GPIO.setmode(GPIO.BOARD)
GPIO.setup(LED_PIN,GPIO.OUT)
while True:
print("LED is on");
GPIO.output(LED_PIN,GPIO.HIGH)
time.sleep(1)
print("LED is off");
GPIO.output(LED_PIN,GPIO.LOW)
time.sleep(1)
GPIO.cleanup()

 

$ chmod +x ./ledblink.py
$ sudo ./ledblink.py
