Please explain the bit about getting the temperature from the solenoid. A solenoid is an electromagnetic component which produces a force. Is does not tell you anything about the temperature. To read the temperature you would need a temperature sensor - there are various ones about that can interface easily with an Arduino. Perhaps your translation has picked the wrong word for this component?I attached my solenoid , when the current cross it the iron get hotter than before >
Your answer makes no more sense to me than the original post. By 'solenoid' are you talking about a wire wound component? Is this a sensor or something you are trying to control? If it's a sensor, what does it sense and how? If it's something you're trying to control, what does it do and what are you trying to do with it?
