Interfacing of Raspberry pi with led and Switch

Interfacing of Raspberry pi with led and Switch:

Now ready to write code to switch and Led.  Turn on your Raspberry Pi and Open the terminal window.

Create a new text file “switch1.py” by typing the following:

Sudo nano switch1.py

After that write following code to the Text editer page:

import os

import RPi.GPIO as GPIO

from time import sleep

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BOARD) #board usage gpio pin , bcm usasge pin mnumber

GPIO.setup(3,GPIO.IN)

GPIO.setup(5,GPIO.OUT)

print(" interfacing of Switch and Led")

while True:

    if( GPIO.input(3)== False):

        print("Switch is Pressed")

            GPIO.output(5,GPIO.HIGH)

            sleep(1)

           

    else:

        GPIO.output(5,GPIO.LOW)

            sleep(1)

        sleep(2)

       

After writing the code we checked it, save and exit the text editor with

 “Ctrl + x” then “y” then “enter”.

To Running this Code Type:

sudo python switch1.py

then

You will see the LED turn on when switch is pressed.
