i want to modify this circuit to fuction for the fridge so it should work like a digital theromoter swtich connected to fridge compressor so it that will monitor a refrigerated room. it should effectively turn off the compressor of the fridge when the temperature is lower or equal to -5 degree Celsius and it will turn it back on when temperature is greater than -5 degrees Celsius. It should also give sound warning signal when temperature exceeds the 0 degree Celsius.
plz can somebody help in telling me what compents should be replaced here. for the new diagran according to the new requirments.
