Hi all
I want to detect a 12V signal using an Arduino Nano v3.
I've decided to use a NPN transistor to do so. Is it a valid solution?
I've tried the circuit and it looks like it works fine.
I've tried to use the 100k res at the base but I don't really know if it's the best value. How to chose it?
Thanks
