The purpose of this circuit is to indicate temperature using several LEDs and a buzzer. One LED at a time is illuminated for 31ºC, 33ºC, 35ºC, 37ºC, and 40ºC. 40 and 37 degrees were chosen because of the project specification, the others because they would yield roughly equal voltage differences which would simplify the final design.
