Step 1: Setup

Connect led and Pushbutton as per Video or Photo and write the code and change it according to your connection on breadboard.

Step 2: Install Libraries for GPIO

$ sudo apt-get update

$ sudo apt-get install python-rpi.gpio python3-rpi.gpio

Step 3: Python Program

import RPi.GPIO as GPIO

import time

GPIO.setmode(GPIO.BCM)

GPIO.setwarnings(False)

GPIO.setup(18,GPIO.OUT)

print "LED on"

GPIO.output(18,GPIO.HIGH)

time.sleep(1)

print "LED off"

GPIO.output(18,GPIO.LOW)
