I wanted to control the fridge compartment of my fridge and freezer Combo (Fisher & Paykel E521T). I am thinking of removing the 12v DC Fan with PWM and 12v Low ambient heater with PWM from fisher & paykel motherboard and connect it to BrewPi Spark v2.
I just found this online:-
From my understanding:-
Sprak v2 5v pin (PWM) connect to the TIP-122 Base (B) pin.
The 12V fan connect to the TIP-122 Collector © pin and the Emitter (E) pin connect to the Ground.
Will PWM work if I connect it to BrewPi Spark v2 this way?
Thanks in advance.
