This project uses HK32F030MF4P6 microcontroller to control the color of RGB lights through 3 I/O ports, use 7 I/O ports to control the lighting of RGB lights, and use two I/O ports to control the lighting of small white lights and small yellow lights. lamp. At the same time, pins are used to connect the I/O port of the microcontroller, which facilitates later expansion and also has a supporting effect. In addition, the project is equipped with two independent buttons, which can be used to control RGB lights to achieve different effects. Use USB interface for power supply and programming. This is my first time drawing a board, and there are a lot of things that don’t work well. Please give me your valuable opinions. (Postscript: Due to my poor soldering skills, the pins of the MCU were crooked by me, causing the colored lights to not light up. I will make another one when I have the opportunity later.)
