Remote control car based on Liangshan School

Project introduction:
Jialichuang made free boards within 10X10. Due to limited funds, we used two coupons to make the extended version and the trolley bottom plate. The busbar position of the trolley bottom plate and the extended version plug-in position must be perfectly matched.
It has Bluetooth remote control function, four-channel RGB lights, eight-channel PWM control of four motors, and two-channel PWM reserved.
Detailed function introduction:
1. The author of Bluetooth remote control
is relatively new. I used HC-05 in the tutorial, so I bought it. At first I thought I needed to buy a USB to TTL converter, but after struggling for a long time I found that I could use the DAPlink sent by Liangshan to initialize it. . . .
HC-05 can be used after initializing it with AT commands. Because I don’t know much about it, I bought a master-slave one. What I use here is the slave mode. The relevant information provided by the seller is quite detailed. No matter where you buy it from, the merchant will provide it.
APP: 2. The RGB lantern
is used as a headlight. It is also very colorful at night. It can be controlled by IO port or PWM. PWM is used here, you can do whatever you want.
What I bought is a 10mm common anode in-line RGB lamp:
it was originally intended to be used for light tracking and automatic return, but it requires PID and two-channel ADC acquisition. The author's level is limited. I will update it after I understand it later. . . . . . . . . . . . .
Finally, let me show you the actual picture:
