After seeing some amazing DIY controllers, I'm gonna have a go at it. Just had my Arduina Mega and 3.2" touchscreen delivered yesterday.
The plan is to monitor Temp, pH, dissolved Oxygen and eventually filter output flow. Want to also be able to control my heater, Co2, and LEDS with this controller.
I have never written code before, so this is going to be a learn as I go project
Used an existing sketch (Jarduino 1.1) to test everything out, and to give me an idea on how all the code ties in together.
