I am trying to make a simple LED light (Triple Output High Power RGB LED and FemtoBuck LED Driver) for my greenhouse following the above pic from your website. (Yes I have no experience in electronics until today. So please be kind!) However, I will need to a timer for it. Also it seems like I will need a heatsink to go with the LED light. Can I just have some (beginner level) instructions to add a timer and heatsink in?
Putting efforts to try to make a DIY raw looking set rather than a commercial growlight.
here is a heatsink that you could use on the back of your LED:
you can stick it on with this thermal paste:
For a timer, if you want to keep it simple, I would recommend plugging this into a wall timer. If not here are some cool arduino relay timers that could work for you
