LED light panel

1. Introduction:
Are you ready to begin learning hardware circuits? Hardware learning is inseparable from PCB design, so learning to use JLCPCB EDA for PCB layout is essential. Starting with a simple LED circuit, you will learn some basic usage methods of the JLCPCB EDA editor, PCB circuit design, and PCB board fabrication, etc.
2. Schematic: The schematic
uses three LEDs connected in a common cathode configuration, using a header pin as the power input. When the input is high, the LED conducts. The header pin can be connected to the development board to create an LED running light effect using a microcontroller.
3. PCB and Soldering:
When designing the board outline, you can import DXF files to make the outline more than just a square shape. You can add your favorite silkscreen or images to the board; you can also open windows to make the pattern silver for a more sophisticated look.
Components are very easy to find: three free LEDs, three free resistors, and one header pin. Soldering may be difficult for beginners, but the circuit content is simple and the soldering difficulty is low, making it very suitable for beginners.
