  • How to control an arduino car via Bluetooth (for beginners)

    I am interested in the horn part :).Could you please send it to me? stanbogdanandrei22@gmail.com

    Hello,I am wondering if someone could help me...I build the RC Car according to this tutorial, and it 's working as expected except with one minor issue... the motor spin is not as fast as I hoped so... the car is very slow, maybe 1 full spin per 2 seconds.I used the exact motors as it was used in this tutorial, the same motor driver L293D and Bluetooth module HC-05.The motors support max 6V and 300mA to full capacity, and the L293D driver can provide 600mA per motor, so this is not the issue. The two motors are connected to motor1 and motor2 inputs of the driver. The arduino board is powered by an external battery via USB of 5V, 1A. The motor shield is powered directly from arduino (the jumper is included).I used the same code and library as in this tutorial with little modifications ...see more »Hello,I am wondering if someone could help me...I build the RC Car according to this tutorial, and it 's working as expected except with one minor issue... the motor spin is not as fast as I hoped so... the car is very slow, maybe 1 full spin per 2 seconds.I used the exact motors as it was used in this tutorial, the same motor driver L293D and Bluetooth module HC-05.The motors support max 6V and 300mA to full capacity, and the L293D driver can provide 600mA per motor, so this is not the issue.
