Arduino to control frequencies with induction coupling?
I want to experiment with inductive coupling, I have made two similar pancake coils of 16 turns of 12 AWG wire(I had it around ) . Now I need to generate a frequency, I know I can generate one with an arduino but I want to generate one to work with the 12v input from a computer PSU to make it more practical. Any way to do this? I'm kinda new to coils/frequencies.
