Arduino Controlled 50W LED / UV Light with Timer and Brightness Control

This is a 3D-printed programmable high-power LED / UV controller designed for DIY, workshop, curing, lighting, and experimental projects.

The system uses an Arduino Nano with an OLED display, adjustable brightness, programmable countdown timer, active cooling, and real-time voltage/current monitoring.

The front section is modular, allowing you to install either a high-power white LED or a UV LED, depending on your application. Only one LED module is used at a time. The output voltage and current of the CC/CV boost converter should always be adjusted according to the specifications of the LED being used.
