Hi
I'm making a really simple school-project, a circuit that makes hot temperatures turn a fan on and off.
I'm using a resistor, a thermistor, a relay and a transistor.
I managed to get it to work ages ago, but now it doesnt. I can only get a voltage when I connect it across BOTH resistors, not just one (Vout = Vin x R1/R1+R2)
any clues? I've only got a week!!!!!!!!!
