M5Stack Light Sensor Unit

The M5Stack Light Unit has a built-in photoresistor, with which you can measure ambient light. The resistance of a photoresistor decreases with increasing light intensity and vice versa. The light sensor can be read out analogously via the ADC or via a digital input. If the sensor is read out from the M5Core via the digital input, the threshold value where the signal switches can be adjusted via the potentiometer.
