This project demonstrates how to control an **electrical relay module** using a **push button** and an **Arduino UNO**. When the button is pressed, the relay activates; when released, it deactivates — a foundational project for learning **home automation** and **device control**.
This project demonstrates how to interface a **push button switch** with the **Arduino UNO (ATmega328P)** using **register-level programming**, without any Arduino functions.
A simple digital input-output project where an LED is controlled by a push button. When the button is pressed, the LED turns **ON**; when released, it turns **OFF** — the perfect beginner exercise to understand digital logic and I/O pins on Arduino.
This Arduino project demonstrates how to control the direction of a DC motor using two push buttons.
