Christmas Light controller

Typical store bought controllers are garbage…. And professional ones are expensive… so I made my own.

Seen here: a bank of relays and an Arduino


Close up of the relays, this board can be purchased on amazon for around $20, I got mine at a local store called vetco, link here: http://www.vetco.net/catalog/product_info.php?cPath=640&products_id=12829


Close up of Arduino and RTC module, they can both be purchased on amazon, or at vetco

Arduino:  http://www.vetco.net/catalog/product_info.php?cPath=640&products_id=13665

Rtc:   http://www.vetco.net/catalog/product_info.php?cPath=640&products_id=12866


Overview of the entire device, please note that due to the amount of plugs I used, if every one were to be used I would recommend switching to 240 V instead of 110V. When using 240 you can use 1 leg for half the light and the other for the rest, this will ensure you do not over tax the breaker. Please keep in mind that I used a WatStop to verify I was not pulling to many amps with this system.

 

 

Below is a link to a zip files containing all the code I have to the light, please not he code is rough and does need refinement, this code is open source, so use it however you wish.
