Arduino Bluetooth Controled RC Car

In this instructable I am going to show you how to make Bluetooth controled car with 2 DC motors.

Step 1: Materials

Materials:

1.2x DC motor

2.L298N (motor controler)

3.Arduino Uno (or clone)

4.HC-05 (bluetooth module)

Step 2: Chassis Editing

I cut off Middle plastic part and replaced it with wood, then I added 4x1.5V battery pack in the middle of it.

Step 3: Wiring Scheme

Connect one motor to the OUT1 and OUT2 pins of L298N, connect second to the OUT3 and OUT4 pins.

Connect positive wire of batteries to +12V pin and negative to the GND of L298N, then connect same GND to GND of arduino.

Pins of HC-05 are conected to arduino like this: GND to GND; VCC to 5V; RX to TX and TX to RX.

Pins of arduino 8,9,10,11 are connected to IN1,IN2,IN3,IN4 of L298N.

Step 4: Connecting

Connect wites like in prevous step.

Step 5: Upload Code to Arduino

Connect your PC to Arduino and upload this code.

Step 6: Download App

Step 7: App

Turn on your car.

Open app, turn bluetooth on and connect it to the HC-05.

Step 8: Done

Special thanks to "Srpska Nauka", he helped me build this car.
