STEP 1:
Open LX-Terminal.
Create a file with .py extension
Ex: nano
userinput.py
Nano is a type of editor used to write the code in
that file named userinput.
Type the following code in that file by insert key or by typing letter I on keyboard.
STEP 2:
Program:
#! /usr/bin/python
Import os
Import time
Import RPi.GPIO as GPIO
GPIO.setmode (GPIO.BCM)
GPIO.setwarnings (False)
GPIO.setup (17, GPIO.OUT) //configuring 17th
pin as output
GPIO.setup (27, GPIO.OUT) // configuring 27th
pin as output
#Setup variables for user input
led_choice = 0
count = 0
os.system (‘clear’)
print “which LED would you like to blink”
print “1: Red?”
print “2: Blue?”
led_choice = input (“choose your option: “) //user choice
if led_choice == 1: //
select led to blink
os.system (‘clear’)
print “You picked the Red LED”
count = input (“How many times would you
like it to blink? : ”) //user
enter purpose
while count > 0 :
GPIO.output
(27, GPIO.HIGH)
time.sleep (1) //to
sleep for one second
GPIO.output (27, GPIO.LOW)
time.sleep
(1) // to sleep for one second
count
= count-1
if led_choice == 2: // select led to blink
os.system
(‘clear’)
print
”You picked the Blue LED”
count
= input (“How many times would you like to blink? : ”) //user
enter purpose
while
count > 0 :
GPIO.output
(17, GPIO.HIGH)
time.sleep
(1) // to sleep for one second
GPIO.output
(17, GPIO.LOW)
Time.sleep
(1) // to sleep for one second
count
= count-1
Save the file by typing :wq
and then press enter.
To check the
output:Type python userinput.py
Output 1:
Output 2:
Output 3:
Output 4:
