I inverted a polarity (duh!)
so I'm getting a constant +4/5v from the first opamp, and a constant 8.45 from the second (obs: I'm not using a 1m pot as in the scheme, but a 100k)
I need to make the comparation work so that when the temp is lower than the voltage divider, nothing comes out of...
Hello all
I'm trying to build a thermostat with 2 opamps, the first amplifies the analog voltage and the second as a comparator. the comparator should give me a v output whenever the ref (coming from the voltage divider) is higher than what's coming out from my Lm358 configured as hysteresis...
