How to mange the on board relay

GPIO used

  • GPIO34

Manage the relays using RPi.GPIO

Save this source on a file calles relay.py:

import RPi.GPIO as GPIO
import time

RELAY=34

GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(RELAY,GPIO.OUT)

for i in range(5):
    GPIO.output(RELAY,GPIO.LOW)
    time.sleep(0.5)

    GPIO.output(RELAY,GPIO.HIGH)
    time.sleep(0.5)

GPIO.output(RELAY,GPIO.LOW)

The launch it by typing:

python relay.py
