Push-Buttons are normally-open tactile switches. Push buttons allow us to power the circuit or make any particular connection only when we press the button. Simply, it makes the circuit connected when pressed and breaks when released. A push-button is also used for triggering of the SCR by gate terminal.

Components Required :

1.Raspberry pi

2.Breadboard

3. Connecting wire

5. Power Supply

5.Push Button Switch

shows how to connect a tactile push switch using a breadboard and jumper wires.

Code Push Switch Raspberry pi:

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.IN, pull_up_down=GPIO.PUD_UP)
while True:

    input_state = GPIO.input(18)
    if input_state == False:
    print('Button Pressed')
    time.sleep(0.2)

You will need to run the program You can see: Button Pressed Button Pressed ou may take note that the switch is wired so that when it is squeezed, it'll interface Pin 18 arranged as an input to GND. The input PIN is regularly pulled up to 3.3V by the discretionary contention pull_up_down=GPIO.PUD_UP in GPIO.setup. This means that once you examined the input esteem utilizing GPIO.input, Untrue will be returned in the event that the button is squeezed.

Typically a small irrational. Each GPIO pin has software-configurable pull-up and pull-down resistors. When using a GPIO pin as an input, you'll design these resistors so that one, either, or not one or the other of the resistors

is empowered, utilizing the optional pull_up_down parameter to GPIO.setup. In case this parameter is excluded, then neither resistor will be empowered. This takes off the input floating, which means that its esteem cannot be depended upon and it'll float between tall and low depending on what it picks up within the way of electrical noise. If it is set to GPIO.PUD_UP, the pull-up resistor is empowered; in the event that it is set to GPIO.PUD_DOWN, the pull-down resistor is empowered.
