Code for project like a circuit which have two sensors at its two ends which connected to an arduino whenthose to sensors will get higher temperature differnce they send signal to the arduino and thenthe arduino send current to other device in this way it work as generator
secondly when we give voltage the it give arduinoa signal a it will trun on a fan for colling or a burner to raise the temperature.
and a video of the code working in simulation in TinkerCAD
