6V from 5V USB/Projects

Post by timothyreese »

Hello! I'm doing planning now on a medium-sized controller project.

I'm hoping to run the entire thing off of a laptop or something similar, and using the Feather.

The issue I've run into relates to some buttons I'm a huge, huge fan of. They use 6V, 12V or 24V LEDs, but I don't have much experience with anything other than 5V. I need to be able to turn them on and off individually (from the Feather/software), and run about 50 of them. I can't change the LED voltage myself (besides selecting from those three choices), and I really want the buttons, so I'm committed to working out the engineering on it.

Does anyone have any suggestions on a direction to go in? I thought about using a computer power supply for the 12V, and then I guess I would run a relay for each LED? So I could trigger them from the Feather? If that reads confusingly, this is new territory for me in engineering. I've never worked with DC-DC converters, or transistors.

Any, and I mean any tips would be greatly appreciated.

You could use these. They can be chained together to control lots of leds and can accept a higher voltage power supply for the leds.

Bill to the rescue again! Thanks so much!
