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 |
