I'm still kind of new to the raspberry pi, but familiar with turning an LED on/off using the command line or a python webserver. I have a Model B Revision 2.

I've been asked to do a project that choreographs 14 strands of lights to music. I was inspired to use my RPi, after seeing a blog post by Chivalry Timbers, but I do not know how to control more than 8 channels using my RPi. I know it's possible, but need some guidance to get started.

My understanding is that I can use any 14 of the GPIO ports mapped here (http://www.raspberrypi.org/documentation/usage/gpio/images/basic-gpio-layout.png) and wire each of my 14 GPIO ports to 1 of the relays on a relay like this one (http://www.amazon.com/SainSmart-16-CH-16-Channel-Relay-Module/dp/B0057OC66U/ref=sr_1_fkmr2_1?ie=UTF8&qid=1410787622&sr=8-1-fkmr2&keywords=16+channel+relay+for+raspberry+pi). I can then connect the relays to electrical sockets like Chivalry Timbers did, in order to power the light strands on or off.

Am I on track? I'm still a NOOB when it comes to transistors, resistors, but have a basic understanding of electronics. Can anyone provide some guidance for me?

EDIT I should note that, while I understand conceptually how to do this with up to 8 relays, I've never actually done it myself (yet).
