This kit delivers all the electronics and software scaffolding to turn a Raspberry Pi 4 into a deployable, four-channel automation brain that orchestrates heater relay activation, daylight-mimicking grow lights via RTC schedule, an auto top-off pump, and a servo-based feeding mechanism—all written in Python you control.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble and program a fully functional freshwater or marine aquarium controller. The system reads two DS18B20 waterproof sensors at different tank depths, triggers a heater relay when temperature drops below a setpoint, runs a high‑PAR LED or T5 fixture on a precise DS3231 real‑time clock schedule, activates a peristaltic pump for top‑off when a float switch or capacitive sensor indicates low water, and dispenses a measured amount of flakes via a hobby servo at programmed times.
