Aquarium Control & Monitoring - Arduino Project Hub

Project aims to control lights and CO2 admission to a planted aquarium. User has 2 lights time interval to set and one CO2 time interval. In the defined time intervals relays that control lights and CO2 are turned on or off. Additional sensors were added to read data about the aquarium and room. So far so good. The interesting part of the project is still to come: the time intervals, relay controls and sensors data are …
