DIY Light Controller Shield for the Arduino 2560 (Mega)

Hey Guys!

I recently finalized my DIY Home Automation project with great inspiration from Mr Oxer.

I created 2 shields for the arduino mega that can control 21 relays and have inputs for 20 switches through Patch Cables.

Here are my two videos, please let me know what you think. I credited SuperHouse in both videos as great inspiration for them, and would like to thank Mr. Oxer for the great work he has done over the past years.
