Arduino Bluetooth control car with Front & Back Lights using Arduino UNO, L293D Motor Driver, HC-05

This is no final version. The video is just uploaded to youtube. The detailed article will take around 1 week to finish. But if you know the basics this information is enough for you to make the car.

Enjoy:)
