TCS3200 Colour Sensor Board

Sensor

Sensor board that measures an object's colour with red-, green- and blue-filtered photodiodes; four white LEDs light the object. It gives the strength of the chosen colour as a frequency, which the Arduino measures with pulseIn. For colour-sorting machines and robots that recognise colours.

• Colour Detection with the TCS3200Intermediate30 minA circuit that tells the colour of an object held in front of it. The TCS3200 board measures light through red, green and blue filtered photodiodes and puts out the chosen colour's strength as a square wave; the Arduino times the three colours' pulses with pulseIn, prints them to the Serial Monitor and names the strongest. It teaches choosing a filter with digital pins and timing pulses. No extra library needed.Open project
