Blinking a LED With Raspberry Pi

Today i am going to post how to blink a led with raspberry pi. Blinking a LED is a beginner task and simple task.

components required:

• Raspberry pi.
• 2 Male to female connectors.

• A 330 omh resistance.
• A LED.
• A breadboard.

Here is pin diagram of Raspberry pi 2.

• Connect 11th pin to one end of resistance.
• Connect ground pin to -ev pin of LED.
• Now connect remaining end of resistance to +ev of LED.
• Now turn on Raspberry pi.
• open text editor and paste following program into it.

import GPIO.RPi as GPIO ##import GPIO library

import time

GPIO.setmode(GPIO.BOARD) ##use board pin numbering

GPIO.setup(11,GPIO.OUT) ##set 11th pin as output pin

while 1:

GPIO.output(11,1) ## Turn on led

time.sleep(1) ## 1 second delay

GPIO.output(11,0) ## Turn off led

time.sleep(1)

• Save above program as blink.py.
• Now run above program as root user and you will see blinking led.
