+  AS7262 color sensor
+
+  Reads light readings and temperature readings from AMS AS7262 sensor.
+  Uses Sparkfun's AS726x library. Works with both Sparkfun and Adafruit 
+  breakout boards.
+
+  Datasheet: https://cdn.sparkfun.com/assets/parts/1/2/2/4/9/AS7262_Datasheet.pdf
+
+   Visible wavelengths:
+   450nm: violet
+   500nm: blue
+   550nm: green
+   570nm: yellow
+   600nm: orange
+   650nm: red
+
+   According to the datasheet, all channels tested under 5700K White LED light.
+
+   based on Sparkfun libraries
