Today we will be working with two different color sensors. I’ll show you how they work, how to hook them up, how to calibrate them, and how to extract RGB values from them.

The TCS230 (also known as the TCS3200) is a popular and inexpensive color sensor that operates on a wide voltage range. It outputs a square wave whose frequency reflects the color intensity.

The Sparkfun ISL29125 is a more capable sensor that provides a 16-bit digital output using the I2C bus. It also has a programmable interrupt feature that you can set to trigger in response to a specific color.

Both of these sensors will be useful in designing color-following robots, Rubik's Cube solvers or jelly bean sorters. But before you use them you’ll need to calibrate them.

I’ll show you how to calibrate the sensors and then use that calibration data to extract actual RGB values from them.
