Automation of a freshwater aquarium, with an Arduino board.
This project was made a long time ago, and this code may no longer be operational. Furthermore, this code is really not sexy (3K lines code in one file ...) and not maintainable, but could help people to do the same. Keep in mind, i found this code in an old hard drive and it was written in 2011.
This was a project maded for managing a freshwater aquarium, and configurable with a touchscreen user interface. It can:
- manage potential hydrogen (pH) of the water by controlling a solenoid valve on a carbon dioxide cylinder.
- manage a led lighting to match with true cycle of photosynthesis, and true cycle of intensity and wavelenght of the sun rays (sunrise, sunset, moon light etc...).
- manage internal temperature and display external temperature and moisture.
- manage the filtration.
- manage the injection of liquid fertilizer with peristaltic pump.
- renew the water with peristaltic pump.
- Feed the fish with diy mechanical feeder.
- All this was configurable in the user interface.
