More Raspberry PI LED examples in python

by iainhendry71

In our previous example we flashed an LED on, here are another couple of examples

This will flash the led on and off

(adsbygoogle = window.adsbygoogle || []).push({});
 
 
import RPi.GPIO as GPIO
import time
 
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BOARD) ## Use board pin numbering
GPIO.setup(7, GPIO.OUT) ## Setup GPIO Pin 7 to OUT
 
state = True
 
# endless loop
while True:
 GPIO.output(7,True)## Turn on GPIO pin 7
 time.sleep(1) ## 1 second
 GPIO.output(7,False)## Turn off GPIO pin 7
 time.sleep(1)## 1 second

And no we will flash the LED 3 times

import RPi.GPIO as GPIO ## Import GPIO library
import time
 
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BOARD) ## Use board pin numbering
GPIO.setup(7, GPIO.OUT) ## Setup GPIO Pin 7 to OUT
 
for i in range(0,3):## Run loop 3 times
	GPIO.output(7,True)## Switch on pin 7
	time.sleep(1)## Wait 1 second
	GPIO.output(7,False)## Switch off pin 7
	time.sleep(1)## Wait 1 second
