O2Surplus! You pimp! Love the LCD integration, very nice work. I don't even have a fishtank at the moment, having sold everything off before I moved across the country this month. But I'm...

The serial doesn't really send anything unless you "talk" to it with the client.py script I supplied in the code.

If you run the client.py script and enter "time" at the prompt, you get no...

Sorry for the delay in replying!

The RTC communicates over I2C, so you just use whatever pins those are on your board. On the Duemilanove that I have those are A4 and A5. It might be different...

It is a convention in C to name constants starting with a lowercase k. It helps distinguish later on things that should be constant from things that can be safely reassigned. It is not a...

Theoretically, but it is awkward. For example, messing with the settings for Timer0 will affect built in functions like delay() and millis() because they get their timing from it under the hood. ...

The TimerOne library is only there to provide high-resolution output -- if coarser control is fine for your other channels you don't need libraries for them. Dimming for other channels would be the...

That has been a common request. I may end up adding a binary (just off or 5V) moonlight output eventually, but I am hesitant to add too much complexity. In many ways, the code is already more...

I know I haven't been around much, but I'm thrilled to see people are still using the code!

The main reason there is no auto-daylight savings code is that a library to do that (if a clean one even...

I should point out that if people want to run my code on the Typhon, they can, with probably a few very minor modifications that I could help with. There would be some limitations -- the LCD...

Ah, my misunderstanding. My comments above apply to my code only.

I stalled on that point because the LCD control code in the Typhon firmware was such a spaghetti mess that to get the good stuff...

This is pretty cool. It wouldn't be too hard to implement if there is sufficient interest from people. I think I like having a nice consistent 12hr day in my tank though -- it lets me pretend I...

Ok good. I just want to make sure are were using the latest version of tank_control.pde, with I assume the minor modification on lines 48/49 to use the DS1307. This is correct?

Something else is wrong. What sketch is loaded on the Arduino? Usually when this happens it means the reset is also resetting the time on the RTC, either through the sketch or though power cycling...

Hi Gisimo, Currently the libraries I use don't work on Arduino 1.0, so you need to use the version previous to that (22 or 23). Don't worry -- you aren't really losing any functionality when you do...

OK. By the way, 24VDC is a common supply voltage. It's also convenient for LEDs (you can drive a string of 6 x "3W" LEDs with it). So if I were you I'd design my circuit around a suitable 24V...
