New Year RGB Light Board

I. Preparation:
Setting up the computer environment:
1. JLCPCB EDA Web Professional Edition (circuit diagram design).
2. WELD Web Page (code debugging).
Resources: Reference: [LCPCB Panel Printing] Engraved Standee Night Light + Open Source | ESP32C3 Temperature and Humidity Sensor AHT20 + SHT30
II. Code Debugging and Firmware
Burning:
1. Access the website and click Install:
2. Connect to the COM port:
3. Select INSTALL WLED:
4. Click INSTALL:
Clicking INSTALL will delete all existing data on the development board.

5. Browser automatic installation: Preparing to install -> Installing -> Installing... -> Installation successful
Mobile debugging parameters:
1. Turn on Wi-Fi and connect to the WLED-AP's Wi-Fi, password: wld1234. A webpage will automatically open for Wi-Fi configuration. Select WIFI SETTINGS to configure Wi-Fi. Alternatively, you can directly click TO THE CONTROLS below to control Wi-Fi.
2. Enter your home Wi-Fi name and password, then click Save & Connect on the upper right to save the configuration.
3. At this time, you can see the IP address of WLED from the router management interface. Enter the address in your browser. Click Config.
4. Click LED Preferences and change the number of LED beads to your actual number. Then click Save at the bottom to save the configuration.
IV. Problems and Countermeasures
Hardware:
1. ch340K cannot be fully adapted.
2. GPIO2 and GPIO9 should be pulled up.
3D shell:
Simple shell, no openings, no fixing screws.
Improvement: PCB fixing studs are combined with the shell for fixing.
V. Summary and
Improvement Space:
(1) Add clock function (waste utilization: measure how the voltage and frequency of the old electronic alarm clock drive the electromagnet to control the gear to rotate accurately).
(2) Can be changed to IoT applet control.
(3) Improve the external mirror film
. Refer to the 8-inch light painting EPS12F+WS2812-replace LED beads.
