Alexa and Photon Controlled Hanukkah Menorah

Had to find a good use for replaced 12V AC plastic LED path lights, so why not make them into a menorah controlled by Alexa?

Menorah Control code

Arduino
This is the code flashed on the Particle . You can control either individual LEDs or use it to set the day in which all LED equal or less than the number specified with be lit
