Arduino Bluetooth Remote Controle Car Arduino Bluetooth Remote Control Car with Android Smartphone Arduino Bluetooth Remote Controle Car

Arduino Bluetooth Remote Control Car Its an old RF R/C toy car that i convert it to Bluetooth R/C controlled from a Smartphone with an application that i made with MIT App Inventor. For the movements i use the Smartphone's internal orientation sensor and some buttons to turn on/off the lights, to activate the horn, to change "gears" and to connect to Bluetooth module of the car.

For the car i removed all the electronics except the motors and i installed 6 new AA 1,2V rechargeable NiMh 1900mAh batteries. I designed new electronics based on Arduino with a HC-05 Bluetooth module and two h-bridge ic's. The SN754410 for steering motor and the L298N for forward/backward motor. For both ic's i connected parallel the channels, 1 with 4 and 2 with 3.

Here are some pictures of the building procedure
