【Training Camp】A dog retreats

 
Overview
Xiaojian Zhong: It uses hi3861 as the main chip, the servo driver is PCA9685, and the servo uses MG90S.
There were some minor problems in this drawing, such as: the silk screen printing of the PCB burning pin header was wrongly marked, and the pins of the button were not connected correctly when connecting. As a result, the button was always in a conductive state after power was turned on and could not work normally.
I have just started to learn programming, so I will use the example program.
