Hello,
i want to make a pid to control temprature to a small box using a resistor (i saw someone use a resistor 10ohm 5 watt) for heating and he use the PWM signal and 12V to power by it. and also i will enter the value of Kp,Ki and Kd using a clavier
but i didn't understand the relation between the signal and temperature ?
and what is the maximal temperature could this resistor reach it
i wish you help me with any infos and thank you (and sorry for my bad english)
