This experiment will use a thermistor and the ADC converter on the 9S12 to construct a digital thermometer. The temperature range should be 20 to 40°C. If the current temperature is above the upper limit in the specified range, a red LED should be turned on. You can test this feature by shorting the thermistor leads together (zero resistance). If it is below the lower limit of the specified range, a yellow LED should be turned on. Similarly, you can test this feature by disconnecting one wire of the thermistor (infinite resistance). Otherwise, a green LED will stay on, indicating that the temperature is within the specified range. The temperature measurements will be displayed as fixed-point numbers on an LCD. Design your system with the best possible resolution. The temperature component is 0 to 1 Hz. Experimentally verify the noise level, time-constant, and accuracy of your system.
