Arduino Bluetooth RC remote control car wiper motors

Since the last project of Bluetooth controlled car didn’t work (the original motors of son’s kid car wasn’t enough powerful for me :-)) I’ve decided to build one from scratch

Parts list:
– 2 wiper motors
– 2 IBT2 as driver motor
– HC-05 as Bluetooth module
– L298N as electronic control power supply
– Arduino UNO
– Two mower wheels
– A lot of time
– A patient wife

I use the Android free APP “Bluetooth Electronics”, witch send to HC-05 the string “Roll_Angle,Pitch_Angle”. Arduino estract from this string the angles, convert it into PWM signal to send at the motor driver.

For Pitch_Angle above a threshold, in function of the Roll_Angle, Arduino send a PWM signal greater at one motor instead the other one, so the car can turn in forward and backward movment.

For Pitch_Angle below the threshold, the car turn as a tank.

For the Arduino code or more questions write me
