This video demonstrates a circuit using a temperature sensor, a motor, and an LED. The circuit is designed to activate the motor and LED when the temperature reaches a pre-set threshold. The video shows how to adjust the threshold using a potentiometer and how the circuit responds to changes in temperature.
