STEP 1:
Open LX-Terminal.
Create a file with .py extension
Ex: nano led.py
Nano is a type of editor used to write the code in
that file named led.
Type the following code in that file by insert key or by typing letter I on keyboard.
Program:
To turn on LED’S
#!
/usr/bin/python
Import
RPi.GPIO as GPIO //To import the
RPi.GPIO module
GPIO.setmode
(GPIO.BCM) //Now set the mode to represent the
numbering scheme you prefer.
GPIO.cleanup
() //Return
all channels you have used back to inputs.
GPIO.setwarnings
(False) //Turn off warnings that are annoying.
GPIO.setup
(17, GPIO.OUT) //You need to set
up every channel you are using as input/output. This one is an output
GPIO.setup
(27, GPIO.OUT) //Setup again but this time pin 27.
Print
“Lights on” //To
turn LEDs ON
GPIO.output
(17, GPIO.HIGH) // led
on purpose
GPIO.output
(27, GPIO.HIGH) //led
on purpose
Save the file by typing :wq
and then press enter.
To check output:Type python
led.py
Output 1:

GPIO.cleanup
() //Return all channels you

GPIO.setwarnings
(False) //Turn off warnings that are

GPIO.setup
(17, GPIO.OUT) //configuring 17th
pin as output
GPIO.setup
(27, GPIO.OUT) // configuring 27th pin as
output
Print
“Lights on” //To
turn LEDs ON
GPIO.output
(17, GPIO.LOW) // led
off purpose
GPIO.output
(27, GPIO.LOW) //led
off purpose
To check output:Type python led.py
Output 2:
