Arduino Bluetooth Controled RC Car





Introduction: 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


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

You can download app here:

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.

2 Questions

Hi. Where do you connect the servo motor for steering in the motor controller or the arduino uno? Pls help me!

finished , but car make no response


Finished ,but no response
help me fast

i bought all these items,

i wired according to given...

i uploaded the code...

i connected hc05 with my tab...

but the car make no respones...i is remained stationary

when u upload the code remove rx and tx cables and plug when u done upload the code

Can you send this project pdf format to

Same here can u send it to ? thanks in advance :)

can i use the arduino bluetooth rc car app?

no programa "APK" quais sao as portas do arduino para as luzes da frente e de tras?
