In this project, I built a Bluetooth-based remote-controlled car system using Arduino Uno as the central microcontroller in 2022. The car's movement (forward, backward, left, right, and stop) was controlled through a mobile application joystick via Bluetooth communication using the HC-05 module.

The L298N motor driver was used to control the direction and speed of two DC motors attached to the car’s wheels. LEDs were also integrated for status indicators (e.g., moving forward, reverse, or turning).

This project helped me understand wireless communication, motor control principles (PWM - Pulse Width Modulation), serial communication, and real-world embedded system design. It also strengthened my skills in circuit assembly, mobile-controlled hardware projects, and troubleshooting of electronic systems.
