Detailed Description

Measuring temperature with thermistor.

Example of use:

 #include "mbed.h"
 #include "thermistor.h"

 Serial pc(USBTX, USBRX); // serial communication

 int main() {
     Thermistor my_thermistor(A5, 10000, 3950, 4700); // instantiate the sensor object (on pin A5, nominal resistance is 10kOhms, beta coefficient is 3950 and value of the sacond resistor is 4,7kOhms
     while(1) {
         pc.printf("Temperature: %5.1f celsius degrees\r", my_thermistor.temperature());
         pc.printf("Resistance: %5.1f ohms\r", my_thermistor.resistance());
