Story

In this project, we have used Python GUI along with Raspberry Pi to control an LED. Pin number 8 on the Raspberry Pi has been configured as the output. The code for running this program consists of 2 functions – ON and OFF and 2 Buttons which are used to call these aforementioned functions.

Programming Algorithm:

Step 1:

Import all the necessary packages - tkinter, Rpi.GPIO, time. The package time has been imported in case the function time.sleep is required. However, it has not been used and therefore can be omitted.

Step 2:

Create a window using Tk() and specify its geometry and title.

Step 3:

Set up the GPIO pins and configure Pin number 8 as Output

Step 4:

Define 2 functions to turn the LED on and off

Step 5:

Create 2 buttons in the window and give them the previously mentioned functions as command.

Step 6:

Put the window in a loop.

Code

LED Control Python GUI

from tkinter import *
import RPi.GPIO as GPIO
import time


window= Tk()
window.geometry("1000x600")
window.title("ROBO TEST")

GPIO.setwarnings(False)
GPIO.setmode(GPIO.BOARD)
GPIO.setup(8,GPIO.OUT)


def on():
    GPIO.output(8, True)

def off():
    GPIO.output(8, False)
    


B1 = Button(window, text="ON", width=20, bg="yellow", fg="black", command=on)
B1.place(x=150,y=50)

B2 = Button(window, text="OFF", width=20, bg="yellow", fg="black", command=off)
B2.place(x=350,y=50)

window.mainloop()
