What is Arduino®

Arduino®is an open-source prototyping platform based on easy-to-use hardware and

software. Arduino®boards are able to read inputs –light-on sensor, a finger on a button or a

Twitter message –and turn it into an output –activating of a motor, turning on an LED,

publishing something online. You can tell your board what to do by sending a set of

instructions to the microcontroller on the board. To do so, you use the Arduino

programming language (based on Wiring) and the Arduino®software IDE (based on

Processing). Additional shields/modules/components are required for reading a twitter

message or publishing online. Surf to www.arduino.cc for more information.

Product Overview

The TCS3200 senses colour light with the help of an 8 x 8 array of photodiodes. Then using

a Current-to-Frequency Converter the readings from the photodiodes are converted into a

square wave with a frequency directly proportional to the light intensity. Finally, using the

Arduino® Board we can read the square wave output and get the results for the colour.

Specifications

•supply voltage: 2.7-5.5 VDC

•dimensions: 28.4 x 28.4 mm

Features

•high-resolution conversion of light intensity to frequency

•programmable colour and full-scale output frequency

•communicates directly with a microcontroller

•single-supply operation (2.7 V to 5.5 V)

•power-down feature

•non-linearity error typically 0.2 % at 50 kHz

•stable 200 ppm/°C temperature coefficient

Connect your WPSE325 to your microcontroller (WPB100) as above.

Download the library and data sheet from our website.

Open the Arduino® IDE and import the three libraries. LiquidCrystal_I2C.h is only needed if

you are also connecting an I²C LCD to your controller.

Load the VMA325_code sketch into the IDE, compile and upload.

Start the serial monitor. You should see a result like this:

Please also read the data sheet of the TCS2300, which is included in the VMA325.zip

available from our website.
