-        The temperature sensor works by delivering a voltage to the ADC4 pin that is proportional to the temperature.
-        From the datasheet, a temperature of 27 degrees Celsius delivers a voltage of 0.706 V.
-        With each additional degree the voltage reduces by 1.721 mV or 0.001721 V.
-        The first step in converting the 16-bit temperature is to convert it back to volts, which is done based on the 3.3 V maximum voltage used by the Pico board.
