[Training Camp_Basic Class] 32-story RGB Guangzhou Tower design based on STC12

[Hardware Update V1.3] Due to feedback from some DIY users, the download program has been detected and the microcontroller cannot download the program (old users can try: reset the button to download the program. Reason 1: Due to the serious shortage of the IO port of the microcontroller, the communication port has to be used. Use it as a function port. Reason 2: Since there is no function restriction on the special port when writing the code, sometimes the program will be broken in the middle of downloading), so the hardware is upgraded. (Instructions for use: To download the program, disconnect the MICRO-USB interface and disconnect the 'T' of the DIP switch to download the program. To work with the microcontroller, turn on the 'T' of the DIP switch to enable normal operation. Run the program) [Preface]

Recently I felt bored and wanted to make something as a gift to my girlfriend. I saw a Guangzhou lighthouse online and thought it was very beautiful, so I wanted to make one as a gift to my girlfriend (O(∩_∩)O haha~).

【principle】

This project uses 520 transparent RGB LED lights with 5mm and 4 pins. In theory, each lamp bead has 16 million colors, also known as 24-bit colors. They are connected to each other, so it can be realized with only one microcontroller and several latches. Control a large number of RGB lights. Using STC12C5A60S2 (DIP40 package) microcontroller as the microcontroller, its practicality is higher than that of 51.

【cost】

The cost of components is about 200+ (the author recommends placing orders at Lichuang Mall for convenience and speed)

❤Lichuang Mall is worth having❤

[Required components]

Warm reminder: You can also place an order directly if there is a BOM on the attached page. If you need RGB, you can contact the author to provide a Taobao link. (For copper pillars, buy copper pillars M3*35+6, copper pillars M3*5+6, and double-pass copper pillars M3*8MM for reference only )

[Lighthouse welcomes the first person to make it. Will you be next? 】

【Precautions】

1. The PCB is double-sided and can be printed for 5 yuan.
2. The first time I make a suggestion, start with the smallest one, and the welding process is extremely demanding, otherwise the welding will be ugly (you know).
3. You have to be patient when doing this. You have to be patient when doing this. You have to be patient when doing this. Say important things three times.
