Colour Detection Sensor

Projects General Guidance
1

I have bought a colour detection sensor from Atlas Scientific and have wired it as mentioned on this page as well as using the code given:
http://www.atlas-scientific.com/_files/code/Arduino-sample-code-EZ-COM-MEGA-RGB.pdf
When I verify it, it says serial3 was not declared. What do I have to add to fix this? Thanks.

Are you using a Mega? or an Uno?

Sorry I didn't mention. I'm using Uno, which I understand I will have to tweak the code slightly if you know what has to be done? Thank you.

With the Uno you need to look to use SoftwareSerial.
