 Simple 6-Channel spectrometer using the AS7262 visible light spectral sensor.
 
-README work in progress.
+The spectrometer collects the temperature calibrated values of each color channel and returns them via a serial connection.
+All data is csv formatted and therefore can be processed easily.
+
+Channels and data include (in measuring order) violet, blue, green, yellow, orange and red (VBGYOR).
+
+Settings include turning the bright, white driver LED on and off; the type of return data (absolute or relative values) and the measurement interval.
+
+Standard Serial Connection is established with a baud rate of 57600!
