The Bike Turning Indicator project provides visual signals for turning or lane changes on a bicycle. Using LEDs and a switch or relay, the system activates a set of blinking lights on the bike to signal turns or lane changes to other road users. This project enhances safety and visibility for cyclists by implementing a simple electronic control system for indicator lights.

The Electronic Letter Box project automates mail detection and notification. It typically uses sensors (like infrared or magnetic) to detect when the letter box door is opened or when mail is inserted. The system can activate an alert, such as a buzzer or LED, to notify the owner of new mail. This project integrates sensor technology with electronic signaling to improve mail management and security.

RF Transmitter Receiver project: building a wireless communication system using RF technology for data transmission over short distances.

The IR Remote Tester project verifies the functionality of an infrared (IR) remote control. By using an IR receiver and a display or LED, this circuit detects and displays signals from the remote. When a button is pressed, the tester shows whether the remote is transmitting a signal, helping diagnose remote control issues.
