Hi, I have a little question which I don't know how to solve right now.
I'm designing a circuit which uses a microcontroller and relays to have a square output. The thing is this output must be able to be either 15V o 24V which would come from somewhere...
I was thinking in using two boltage booster to have both voltages available, but now the question is ¿How do I select which voltage to use (without having short circuits)?
Alternatively, maybe there's a way to just use one booster circuit, and digitally chose between two series of voltage resistors to change the booster output voltage, but the ¿how could I do this?
Any ideas?
(Was I able to explain the problem enough?)
Thanks!
