Building a Bluetooth-Controlled Car Using Arduino
In this project, we'll create a simple Bluetooth-controlled car using an Arduino, a motor driver (L298n), and a Bluetooth module. This car can move forward, backward, left, and right, and we’ll use an app on our smartphone to send commands via Bluetooth to control its movement. Components Needed: Arduino Uno L298n Motor Driver Bluetooth Module (HC-05 or HC-06) DC Motors Car Chassis Jumper wires Battery Pack LEDs (optional for indication) Smartphone with a Bluetooth terminal app Wiring Connections: Motor Driver (L298n) Pins: Connect IN1 to Arduino pin 5. Connect IN2 to Arduino pin 6. Connect IN3 to Arduino pin 10. Connect IN4 to Arduino pin 11. Bluetooth Module: Connect the TX pin of the Bluetooth module to the RX pin of the Arduino. Connect the RX pin of the Bluetooth module to the TX pin of the Arduino. Connect VCC and GND to power the Bluetooth module. Motor Connections: Connect the motor terminals to the output pins of the L298n motor driver. Powering the Motors: Use a...
