Automatic Night Light PCB

What is this?

A simple PCB (Printed Circuit Board) that dims under light conditions and brightens in the dark. The design consists of a diode, 100k potentiometer, 22k resistor, 470 resistor, 1M LDR, NPN 3904 transistor and 2 LEDs. The exact BOM (Bill of Materials) and source code can be found on my Github.

Note: PCB Manufacturer was not selected, therefore no updated constraints under "Design Rules". To apply and use the design, please consult your manufacturer's documentation and make the appropriate modifications (i.e. board size, width, parts, etc).

This design uses THT (through-hole) components but can be altered to include SMD (surface-mount) components as well. To change the THT components, update the footprints to your desired SMD parts.
