Based on the Bluetooth connection and control we've learned so far, and how it works, we have built an rc car. How to make an rc car? The method is as follows. First, connect the pin of the Arduino board to pin 11 of the Bluetooth module, and connect pin 12 and RX. motor A and motor driver A-1A pin connection, motor A and motor driver A-1B pin connection, Connect motor B to motor driver B-1A pin connection, connect motor B to motor driver b-1B pin, and connect motor and motor driver respectively. Then, the two pins of the motor A and B are initialized to the output mode so that the software serial communication can communicate with the Bluetooth module. Save command received in Bluetooth to command. In this way, the command is stored in the Arduino, and the Bluetooth module is used to connect to the mobile phone.
