Simple Arduino Car Using HC-06 Bluetooth Module

The easiest way to build an Arduino car and control it with your android device.

• Laptop with Arduino software.
• Any Arduino. (I am using Leonardo).
• Two DC motors with tires attached firmly.
• An acrylic or plastic piece for the base. (A strong piece of cardboard will do the required work).
• Shield (optional).
• Any motor driver. ( I am using L9110)
• Castor.
• Bluetooth module HC-06
• Bluetooth enabled android phone.
• Power bank or a battery pack to power Arduino.
• Few Jumper wires.
• Any strong adhesive (I am using hot glue)

• Mount the DC motors and the castor on the base.
• Mount all other components positioned correctly.

Bluetooth Module HC-06:

TX to Pin 10 (of arduino)

RX to Pin 11

GND to GND

VCC to VCC

Motor Driver To Motors (left and right):

A1 to Left Motor -ve

B1 to Left Motor +ve

A2 to Right Motor -ve

B2 to Right Motor +ve

Motor Driver to Arduino:

VCC to 5V

GND to GND

B1 to Pin 5

A1 to Pin 9

B2 to Pin 6

A2 to Pin 3

Install it.

Turn on your smartphone's bluetooth and then pair it with the bluetooth module (HC-06). Password: 0000 OR 1234.

Open the app, then select HC-06. Wait until it shows "connected".

Go to settings, then select Keys configuration.

Configure the following commands:

UP = 1

DOWN = 2

RIGHT = 3

LEFT = 4

Select arrow keys and control your car.

DONE !
