Just wanted to start a thread when hopefully people can imput knowledge in to the arduino controller. I am looking in to setting up my led lights with a sun up sun down function. I have noticed there are few people who have had luck. If there is any one out there who could help me out with a sketch it would be great.
There are quite a few of those in the DIY or Lighting sections, my own included. You will, however, require some hardware other than the arduino to make any of them work, I assume you have some idea how to hook it up?
Darkblade is right, if you don't have at least some idea what the electrical part of your project looks like, much more specific help will be difficult to give.
Edit: Most light controller sketches will have up / down fading even if not mentioned specifically.
I got my auto doser working last night! All 3 pumps now run sequentially at a set time. Now I just have work out the timing (milliseconds vs ml) which shouldn't be to hard. It's all soldered up and almost good to go!
I find a wood box for 3$ at the dollar store for mounting it in... a little bigger than I would like but for the price it will do the trick for now
i'm hoping to start playing with a raspberry pi soon.
Have you seen the new BeagleBone Black? It's similar to the Raspberry Pi (an embedded LInux microcomputer), but has way more (48 i think? might be wrong) IO pins, which be much better for adding lots of sensors and controlling tanks, and its only $45.
