Light Detector

The light sensor is an analog sensor that uses a a photoresistor with two FETs to turn on two different LEDs at different lighting thresholds.

Temperature Sensor

The temperature sensor is an analog sensor that uses a thermistor and a series of op-amps to turn on three different LEDs at different temperature thresholds depending on ambient temperature conditions.
