I need a circuit whereby temperature is sensed, and if below a certain value, a heating element makes the temperature rise. And when the temperature reaches that certain value, a motor starts turning.
Any ideas?? =_= are there any precautions to take??
If you want it simple, google for some PTC sensors and op-amps (LM358 f.i.) in comparator mode. the temperature sensor changes it's resistance for changes of temperature. Start playing with op-amps in comparator mode. That's really simple stuff.
