Building a Bluetooth-controlled car project involves a few key steps. Let’s get started:
Assemble the Circuit:
Gather the necessary components:
- Arduino Uno
- L298N motor driver
- HC-05 Bluetooth module
- Two DC motors
- Chassis with wheels
- Battery pack
- Jumper wires
Connect the components as shown in the circuit diagram1.
Upload the Code:
Upload the provided Arduino sketch to the Arduino board.
The code allows you to control the car’s movement using simple characters:
‘F’ for forward
‘B’ for backward
‘L' for left
‘R’ for right
‘S’ for stop
Pair with Bluetooth:
Pair the HC-05 Bluetooth module with your smartphone or computer.
Control the Car:
Use a Bluetooth terminal app to send commands to the Arduino and control the car.
In my case i used Arduino Bluetooth control app.
