Summary of the Circuit
This circuit consists of an Arduino Nano microcontroller, an NTC thermistor (Negative Temperature Coefficient), and a resistor. The Arduino Nano serves as the central processing unit, controlling the inputs and outputs of the circuit. The NTC thermistor is a temperature-sensitive resistor whose resistance decreases as the temperature increases. The resistor is used to form a voltage divider with the NTC thermistor, which allows the Arduino Nano to measure temperature changes through its analog input.
