• Zuino XS PsyFi32 Qwiic Start Guide

Installing Libraries

You need to install the following libraries to your Arduino IDE before you can start programming your Zuino board with Zio Qwiic RGB Color Sensor. 

Download the following libraries and save it on your local Arduino IDE libraries folder:

Adafruit TCS34725 Library

To install the libraries open your Arduino IDE, go to Sketch tab, select Include Library -> Add .Zip Library. Select the above libraries to be included on your IDE.

Connection Set up

Connection with Zuino M Uno

Connection with Zuino XS PsyFi32

Testing Example Codes

We are going to demo our RGB Color sensor using the following example codes. The following examples work with our Zio development boards. Just select the right board and port from the  Arduino IDE platform.

Colorview Example
TCS34725 Example

1.Colorview Example Code

Open your Arduino

Go to File > Examples > Adafruit TCS37425 > colorview

Open Serial editor to view the results 

2. TCS34725 Example Code

This example code will output color temperature values in Kelvin (K), lux values, RGB filtered values and clear values.

Open your Arduino

Go to File > Examples > Adafruit TCS37425 > tcs34725

Open serial monitor to view results
