Hello.
I need your help. I'm controlling some LEDs with my Arduino. That means that I get an output of 3,3V. The LEDs I want to power require 15V. So how can I solve this?
My idea was that I just use a relai (for example the SRD-05VDC-SL-C). Then the 15V would have to come from an external transformer. What do you think? Is that a good idea or is there any smarter and cheaper way?
