This Whisker lets you measure ambient light and color temperature via the TCS3472 Color Sensor and onboard emitting LED. This I²C sensor measures red, green, blue and clear light with 16-bit resolution. The interrupt registers may be used to set threshold values independently for each color register (RGBC) to improve system efficiency and avoid continuous polling of the sensor.
The Whisker Adapter TinyShield (ASD2022) incorporates level shifting and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.
