Hello all,
I am an arduino noob, and am having a heck of a time figuring out how to write a simple script to adjust the brightness of some LEDs depending on the time of day. Ideally, I would like to set it up using TimeLord.h since that seems to be a fairly good library. However, I'm honestly not sure where to even start.
This is the project I'm working on.
And the code used is below (removed some to fit character count, full code here): any guidance on where to start, or even just have it be one value from 6a-6p and a second from 6p-6a would be great.
Thanks in advance for any help!
