An Automatic Room Cooling is an electronic system designed to maintain a comfortable room temperature automatically. It uses a DHT11 temperature sensor to monitor the room, a DC fan for cooling, an LCD to display real-time data, and a buzzer to provide alerts. The system activates the fan automatically when the room temperature exceeds a set threshold, making it an efficient solution for homes, laboratories, and small offices.

A Digital Lock System is an electronic security project designed to control access using a password entered via a keypad. It utilizes an Arduino, keypad, LCD, servo motor, and buzzer to provide a safe, automated locking mechanism. When the correct password is entered, the lock opens; if the wrong password is entered, an alert is triggered. This project is widely used in home security, lockers, safes, and access-controlled systems.

A digital ruler is an electronic measuring device that provides precise measurements of length, width, or depth. Unlike traditional rulers or tape measures, digital rulers use sensors and electronic displays (often LCD or LED) to show measurements accurately, usually in both metric (mm/cm) and imperial (inches) units. They are widely used in engineering, design, woodworking, tailoring, and education where precision is critical.

A Morse Code Generator is an electronic project designed to convert text input into Morse code signals using Arduino, a keypad, and a buzzer. Morse code is a method of encoding text characters as sequences of dots and dashes, widely used in communication systems, especially in emergency signaling and amateur radio. This project demonstrates signal encoding, microcontroller programming, and interactive electronics.

A Reaction Time Game is an interactive electronic project designed to measure a user’s response speed. Using an Arduino, keypad, buzzer, and LCD, the system tests how quickly a player can respond to a visual or auditory signal. This project is widely used in educational setups, gaming, and psychology experiments to study reflexes and reaction times.
