Its an old RF R/C toy car that i convert it to Bluetooth R/C controled from a smartphone with an aplication 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 exept the motors and i installed 6 new AA 1,2V rechargable NiMh 1900mAh batteries. I designed new electronics based on Arduino with a HC-05 Bluetooth module and two h-bridge ic's. The L293D 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.

I will try to upload soon some schematics and code.

Thank you

Looks very cool, nice job! Thanks for the MIT App Inventor mention - looks like a promising tool!

Good video! Very impressive! It looks like you have lots of features controlled by the phone!

Looking forward to seeing your code and schematics.

Wonderful work on the schematics! Thank you for sharing! 

  One comment, your pins are labeled A0 through A10, although you are using an Atmega328... Should those numbers be D0 through D10?  The Uno board has A0 through A5 only.

Thank you  for your nice words.

The AA0 and A2 through A10 labels it is not the pins of Arduino Uno. It is the labels that connect the rest of the schematics with the Arduino schematic.
The actual pins of Arduino Uno is labels A0 and 2 through 10 where is by the lines starting from the rectangular that represents Arduino Uno.
I hope this clears out the labeling. Sorry for not beeing so clear.
