SMD LED Ring Light for Potentiometer
A simple DIY LED ring light for potentiometer/rotary encoder and Arduino, driven by MAX7219 multiplexing chip. A custom PCB was created in KiCad, and ordered together with SMD assembly from PCBWay. The only part that I need to hand solder are the header pins. This module uses 32 SMD LEDs sized 0402 - those are very small and they would be hard to solder by hand. Is my DIY LED ring light cheaper compared to the one that you can buy on AliExpress? Well, it depends. It is slightly cheaper if you order 10 pieces, but it would be much cheaper for higher quantities.
A video describing the creation process:
