Hi Guys, we have a homework that needs to activate DC motor when LM35 reached a certain temperature. I'm struggling to create a schematics since im not really good with electronics. My Idea so far is to use (2 OP AMP Inverting Amplifier to amplify the voltage then compare send the output to another OP Amp Comparator) My problem right now is how it will activate the DC motor? Can someone provide me a simple schematics for this.
