New video! The Adafruit Circuit Playground Express comes equipped with an analog light sensor, but it can be used for much more than just sensing light or darkness! The light sensor has a similar spectral response to the human eye. Its connected to analog pin A8 and will return a value between 0 and 1023. A normal indoor light level reading is about 300, with higher numbers being brighter.
