Wireless remote control car based on Liangshan School development board

Overview

An independent remote control is used to control the movement of the car and turn on and off the light function. The controller uses a Bluetooth controller made from a breadboard and minimal system board flying wires. The car controls the rotation of the four wheels through PWM.
Car hardware part:
Wheels: Mecanum wheel
drive motor: 6V N20 motor
Base plate: 3.6mm acrylic plate
Battery: 7.4v 18650 battery pack
Bluetooth: HC-05 module
fixes the PCB board to the base plate through studs, and the battery Use Velcro to attach the base plate

PCB to the

finished car after welding the Bluetooth and Liangshan faction boards

. The holes on the acrylic plate are reserved for subsequent addition of functions. Use 3D printed parts to fix the motor on the base plate. The motor fixing parts are as shown in
