Step 1: HC-05 Bluetooth Module

The HC-05 Bluetooth Module is responsible for enabling Bluetooth Communication between Arduino and Android Phone.

For more information on HC-05 Bluetooth Module, refer to HC-05 Bluetooth Module.

Step 2: L298N Motor Driver

The L298N Motor Driver Module is responsible for providing the necessary drive current to the motors of the robotic car.

Step 3: Circuit Diagram

The following is the circuit diagram of Bluetooth Controlled Robot using Arduino, L298N and HC-05.

Component required :

Step 4: Android Application

App for voice command control – Download
App for Button and Gesture Control – Download

Voice command app

You can set the voice command and what data to send at that voice command.

I’ve configured 5 voice commands,

Forward & Data = 1

Backward & Data = 2

Right & Data = 3

Left & Data = 4

Stop & Data = 5

Gesture and Button Control App
In this the data sent is fixed by the developer of the app.

Forward – FF

Backward – BB

Right – RR

Left – LL

Stop – SS
