Blink Led using Raspberry pi 3 with Python script.

In this blog, I will explain how to blink a led using raspberry pi 3 with python code.

Components Required

1. Raspberry pi 3

2. Led

3. jumper wires

4. Breadboard

5. 220 ohm Resistor

Circuit Diagram

Step1- Make connection as shown in above figure.
Step2- Connect led +ve pin to 7 pin of raspberry pi and -ve pin of led to 39 pin of raspberry pi.
Step3- Resistor must be connected otherwise led will fused.
Step4- Download the code and upload the raspberry pi.

Program Code

import RPi.GPIO as GPIO

import time

GPIO.setmode(GPIO.BOARD)

GPIO.setup(7,GPIO.OUT)

i = 1

while(i<=5):

    GPIO.output(7,True)

    time.sleep(1)

    GPIO.output(7,False)

    time.sleep(1)

    i = i + 1

GPIO.cleanup()
