I'm pretty new to Pi and electronics.
I need to use my Pi as fans controller. I got two 12V fans and need to control it from Pi. I want to use external power supply (12V) to give them propper power.
I have a ready example that works great, for one device (fan):
But now I need two fans and control it independently, alternately (so as not to overload PI).
- Is it possible to modify this circuit to control two fans?
- Should I make two such circuits and connect them in parallel to a 12v power supply?
- Or maybe make another better layout, someone from 'ekektroda' told me that the circuit is wrong...
