Push Button Counter Using Arduino and LCD

Project Overview

The Push Button Counter is an Arduino-based electronics project that counts button presses and displays the count on an LCD. It demonstrates basic digital input handling, counter logic, and LCD interfacing.

Objectives

• Count push button presses.
• Display the counter value on an LCD.
• Understand Arduino programming and hardware interfacing.
• Demonstrate the interaction between input devices and output displays.

Components Used

• Arduino board
• Push button
• LCD display
• Connecting wires
• Breadboard, if used
• USB cable or suitable power supply

Working Principle

1. The Arduino initializes the LCD and counter.
2. The push button acts as the input.
3. When a valid button press is detected, the counter value is updated.
4. The updated count is displayed on the LCD.
