How to Build a Bluetooth-Controlled RC Car Using Arduino UNO, HC-05, and L298N Motor Driver
Building a remote-controlled car is an exciting way to dive into robotics and electronics. In this project, we’ll guide you through creating a Bluetooth-controlled car using an Arduino UNO , HC-05 Bluetooth module , and L298N motor driver . Step 1: Components You’ll Need Arduino UNO – The brain of your car. HC-05 Bluetooth Module – For wireless communication. L298N Motor Driver – To control motor speed and direction. DC Motors – Two or four motors for your wheels. Car Chassis – A sturdy frame for your car. 5V power bank – To power the motors. Jumper Wires – For connections. Step 2: Circuit Connections HC-05 to Arduino: VCC → Arduino 5V GND → Arduino GND TX → Arduino RX (Pin 0) RX → Arduino TX (Pin 1) L298N Motor Driver to Arduino: Motor-1-FW, Motor-1-BW → Arduino Pins 8, 9 Motor-2-FW, Motor-2-BW → Arduino Pins 10, 11 Power: Connect the 5v power bank to the motor driver’s power input. Share the ground between the battery and Arduino Step 3: Wr...
