+  Arduino LTR381RGB - Measure Calibration Parameters
+
+  This example shows have to be used to measure the calibration parameters.
+  The calibration parameters are the maximum and minimum values for each 
+  color channel.
+
+  To calculate the calibration parameters follow the steps below:
+  - Turn Off all the lights and let the sketch measure the minimum R, G, B 
+    light intensity.
+  - Turn On the light RGB channel one at a time and with the light channels
+    set to the maximum brightness let the sketch measure the maximum R, G
+    and B values.
+  - Take note of the maximum and minimum values and use them in the 
+    ReadCalibratedColors example.
+
+  This example code is in the public domain.
