Hello, Before I begin I just want to say this.. I have NO clue how to upload images from Eagle, other wise this would be a much easier question to ask so bear with me.
I recently built a voltage comparator circuit out of Forest Mims's Basic electronics book (Page 83 for any one who has the book) and modified it slightly to work as a solar tracker. and would like to set the circuit up to control relays. This is what I don't understand: I can find relays that trigger at 5v, (my circuit is 6v) but none of those will handle the current draw from the 12v seat motor I want to control. And this circuit cant come close to triggering a 12v automotive relay, I thouht I would make the circuit 12v to match the motor but I'm not sure it can handle that.
I know I'm missing something obvious, so I've come for advise and input.
please take note*I'm just thrilled to have made this thing work at all!
So to sum it up, tiny circuit, HUGE motor! Avoid smoke....
Thank you to any one in advance who offers there two cents.
