Arduino Uno Push Button

This project demonstrates how to interface a push button with an Arduino Uno.

The Arduino reads the state of the push button and prints a message to the Serial Monitor indicating whether the button is pressed or not.

Components Needed

Connect one leg of the push button to digital pin 2 on the Arduino Uno.

Connect the other leg of the push button to GND on the Arduino Uno.

Optionally, connect a pull-up resistor (10kΩ) between the digital pin 2 and +5V to ensure reliable operation.

Wire up the push button to the Arduino Uno according to the circuit setup section.

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Uno.

Open the serial monitor with a baud rate of 9600.

Observe the output on the Serial Monitor, which will indicate "Button pressed!" when the button is pressed.

Ensure the push button is connected correctly to avoid unintentional triggering.

Consider debounce techniques if the button input is erratic due to mechanical bouncing.

Customize the code to perform specific actions based on button presses as required by your project.
