NTC thermistor is a temperature sensitive ATMEGA48PA-PU resistor
B value: represents the characteristic of the resistance value change of NTC thermistor at two different temperatures.
Series connection method: NTC thermistor is connected in series with other resistors and can be used for temperature compensation in circuits.
Resistance wire is a type of conductor with a specific resistance value,
First, halve the length, so the new length is half of the original: [L' = \frac{L}{2}].
In practical applications, this change in resistance value can be used to adjust the resistance value in the circuit to meet different requirements
