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 color 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

Pin Layout

GND	ground
OUT	output frequency
S0	output frequency scaling selection input
S1	output frequency scaling selection input
S2	photodiode type selection input
S3	photodiode type selection input

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.
