MeepNand Posted June 5, 2013 Share Posted June 5, 2013 Next project, between working on the Ultimate LED Controller: attiny84 based natural aquarium controller. Should only take a few days tops as I already have many of the required components, and the coding is very simple. This is for people that have already have an Arduino or a little coding experience, but even if you don't, you should be able to do this no problem. This is really a good experience for me to learn how to work with small amounts of memory for code. Also, I want to help out the pjreef system with this, and later, a complete smd circuit with no programming required. Planned features: -Pump control (non-adjustable except in code) -Temperature control (non-adjustable except in code) -Natural lighting control (with photoresistor) Later, after Ultimate LED Controller: -LCD display (needs attiny84 for another $5) -Setting changes Hardware -5v power supply -10k thermistor -2 10k resistor -200k photoresistor -10uf 16v capcitor to program with -aquarium silicone to cover the thermistor -Wire (Enough to connect the photoresistor to a window or outside) -2 Filter capacitors (0.1uf ceramic) And of course an Attiny84 (and something to program it with; or you could just use an arduino nano) EDIT: or an attiny44 for $2 cheaper. TOTAL: About $8 + shipping, so about $14. $5.70 more if you use an Arduino Nano instead of an attiny. Software -attiny libraries to program (look it up) -Arduino program (almost any version 1.0+) Notes: -Thermistor table: http://playground.arduino.cc//ComponentLib/Thermistor attiny_controller.txt Link to comment
Cheese-Lover Posted June 9, 2013 Share Posted June 9, 2013 Any chance of using celcius rather than that imaginary system of measurement favored in the states?>.<>.><.<I mean, when I see 75degrees.... I think **** that water is about to start bubbling... Link to comment

I think **** that water is about to start bubbling... Celcius is easy enough. I set it to just under 26.7*C. The thermistor table lists temperatures in Celcius. Link to comment
lizardfish Posted July 14, 2013 Share Posted July 14, 2013 i was thinking about using a 0-10v input dimmable driver and using a small 10v solar cell to control it. but using a photoresistor sounds like a better idea Link to comment
