I am new for raspberry, I have raspberry-3 board and I tried following Python code on it. Which I took from here.
import RPi.GPIO as GPIO import time def blink(pin): GPIO.output(pin,GPIO.HIGH) time.sleep(1) GPIO.output(pin,GPIO.LOW) time.sleep(1) return GPIO.setmode(GPIO.BOARD) GPIO.setup(12, GPIO.OUT) for i in range(0,50): blink(12) GPIO.cleanup()
My circuit looks like this,
Thanks in advance.
