Arduino Bluetooth Remote Control Car with Android Smartphone |
|
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 |

The Schematics
You can have the Arduino Code here
You can have the APK file for the Android here, it is designed for Samsung Galaxy SIII mini, and i dont know how it will look or work to other Android devices.
You can have the source files for AppInventor here so you can modify to your needs.
Don't forget to visit my youtube channel here to check out my other Arduino videos.
