Steinhardt-Hart Equation for computing temperature from a thermistor.
float R1 = 10000; // resistance value of the fixed resistor
float RT; // resistance value of thermistor
float T; // final temperature value
int therm_val; // where you will store the value from analogRead()
// get the value
/* INSERT CODE HERE TO RETRIEVE THE ANALOG VALUE & STORE IT IN therm_val */
// this is the math equation for computing the resistance of thermistor
RT = R1 * (1023 - therm_val) / therm_val;
