My name is Ollie, new to the forum and the world of arduino. I've been keeping fish for many years but have recently decided to dip my toes into reefkeeping. To make life easier with led lights to control and various parameters to monitor I've decided to utilise a controller but given the extortionate cost of off the shelf units and my love of DIY I've opted to build my own. Given my lack of programming experience I'm feeling a tad daunted by the task but looking forward to the challenge.
Goals for the controller: 4x pwm channels for dimming lights. Temperature control for the lights using a temp sensor and pwm fans Multiple relays for both ac and dc switching (potentially up to x16) Temperature control of the aquarium Water level monitoring and top off Spill/leak sensor Warning buzzer for out of limits parameters LCD to display warning Everything referenced to an rtc Pump override button for feeding and maintenance. I'm sure there will be more added to the list as time goes on so I've purchased a mega to make sure I have an excess of everything
