Arduino Aquarium Controller Kit - Automate Heater, Light & Feeding
Build an Automated Fish Tank Controller with Arduino Uno - Control Temperature, Lighting, Water Level & Feeding on Schedule
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine coming home to a crystal-clear aquarium where the temperature is stable, lights follow a natural day-night cycle, water never drops too low, and food dispenses precisely when your fish expect it - all without daily manual intervention. This kit turns that vision into a robust Arduino-based control system you build and program yourself. It's engineered for the Indian hobbyist who faces erratic power, evaporation in dry summers, and the need for fail-safe schedules while away at college or work.
What You'll Build
A fully integrated aquarium controller that monitors water temperature with a waterproof DS18B20 sensor, switches a heater relay to maintain set points, cycles LED lighting via a DS3231 real-time clock, tops off evaporated water using a water level sensor and pump relay, and dispenses food on schedule with a servo. The 16x2 LCD with I2C backpack displays real-time parameters so you can check status instantly without a laptop.
What You'll Learn
- Interfacing and programming an Arduino Uno with multiple sensors and actuators simultaneously
- Implementing precise time-based tasks using a DS3231 RTC for lights, feeding, and water top-off
- Controlling high-power devices like heaters and pumps safely through a relay module with freewheeling diodes
- Debugging and integrating I2C LCD displays to show system status in embedded projects

Who This Kit Is For
B.Tech ECE and EEE students building home automation projects for the Smart India Hackathon or final-year submissions. CBSE Class 12 students exploring IoT through Arduino. ATL Tinkering Lab mentors who need a reliable, pre-tested module for their students. Hobbyists at IIT, NIT, VIT, or BITS Pilani who want a plug-and-build solution for a dorm aquarium that runs on its own during exam weeks.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
Can I customize the feeding and lighting schedules?
Yes, the Arduino code is fully open-source, and the AI companion explains how to adjust feeding intervals, light on/off times, and temperature thresholds. You can modify the schedule to match your fish species' needs.
Will this work during power outages common in India?
The controller resets automatically when power returns, and the DS3231 RTC retains time with its backup battery, so schedules stay accurate. You can add a UPS for the critical heater and pump with the relay module.
Do I need prior soldering experience?
The kit includes a soldering iron and solder wire, and the AI companion provides video guidance on soldering the PCB prototype board. Some components require soldering, but the step-by-step support makes it manageable even if you're a beginner.
What if my water level sensor malfunctions and overflows the tank?
The code includes a safety timeout: the pump relay only activates for a maximum duration each cycle. The AI companion helps you test and calibrate the sensor before full deployment for extra safety.
Controls heater relay, LED lighting cycle via RTC, auto top-off pump via water level sensor and feeding servo on schedule.
