Learn how to create a DIY LED ring light for potentiometer/rotary encoder and Arduino, driven by MAX7219 multiplexing chip. I will create a custom PCB in KiCad, and order it 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.

PCBWay is a service for manufacturing custom PCBs. If you click the link above, you will get a coupon for $5, which is exactly the price of 10 pieces of custom PCBs. In that case, you will only pay for shipping. Do you have any experience doing this? Please let me know in the comment section!
