Make GIU interface for Control LED in Raspberry pi

You want to make an application to run on the Raspberry Pi that has a button for turning things on and off. Today I show you How to Make GIU interface for Control LED in Raspberry pi Step bt step Complet Process.

Required Component connect LED Raspberry Pi :

1.Raspberry pi

2.Breadboard

3. Connecting wire

4.Resistors

5. 5mm LED

shows how you can wire this LED using a solderless breadboard and male-to-female jumper leads

Connecting an LED to a Raspberry Pi

Code GIU LED Raspberry pi:

from tkinter import *
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(12, GPIO.OUT)
class App:
    
     def __init__(self, master):
         
         frame = Frame(master)
         frame.pack()
         self.check_var = BooleanVar()
         check = Checkbutton(frame, text='LED ON Or OFF',
         command=self.update,
         variable=self.check_var, onvalue=True, offvalue=False)
         check.grid(row=1)
     def update(self):
         GPIO.output(12, self.check_var.get())
root = Tk()
root.wm_title('On / Off Switch')
app = App(root)
root.geometry("200x100+0+0")
root.mainloop()

When you run this Code you can see like this interface and Python program that uses a checkbox to turn the GPIO pin on and off

Its initializer function creates a member variable called check_var that contains an instance of BooleanVar that is then supplied as the variable option to the checkbox. The command option runs the update command every time such a change occurs. The update function simply writes the value in check_var to the GPIO output.
