I am trying to brush up on my circuit reading skills. I am at a loss with four mosfets. I also have never seen "peltier", did some research on it, it is temperature controller which makes sense given the application.
I really can only go so far as if motor+ goes above 5V, U1 should go high and "close" 3904 (T1). If we assume that the other motor results in T2 being open, would current then flow through M1 because gate is now tied to ground via short? Then I think T4 and M4 would be active too and other transistors will be off. I really am quite lost...
I will try to go through this again but will appreciate any help.
