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.

We have a be nice policy.
Please be positive and constructive.
My car just turns arount itself, doesn't go forward. How can I solve it? And after some time the app on my phone gets errors. I didn't use servo motor, you didn't list it also but in the codes there is servo why?
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
