Nano Aquarium Controller Kit - Automate Temp, Lights & Feeding
Automate Your Aquarium with the Nano Arduino Controller Kit: Temperature, Light, and Feeding
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Give your fish the perfect environment while you're away. This kit turns an Arduino Nano into the brain of your aquarium, using a waterproof DS18B20 sensor to monitor temperature, a DS3231 RTC to keep accurate time, and relays plus a servo to automate heating, lighting, and feeding. All you need is a 9V battery and a few hours to build a fully functional controller.
What You'll Build
A compact, wall-mountable controller that reads water temperature every second, toggles a heater relay to maintain your chosen range, switches aquarium lights on at dawn and off at dusk based on the RTC schedule, and rotates a small servo to drop a pinch of food at programmed times. The 0.96-inch OLED displays current temp, relay status, and the next feeding time. You can easily adjust all settings later with simple code edits.
What You'll Learn
- Wiring a waterproof DS18B20 temperature sensor to an Arduino Nano and reading one-wire data
- Configuring and reading a DS3231 real-time clock to trigger timed events
- Controlling high-voltage aquarium devices safely using 5V relay modules
- Programming a small servo motor to dispense food at scheduled intervals

Who This Kit Is For
Ideal for parents looking for a hands-on STEM project with their child, for ATL Tinkering Labs wanting a ready-to-solder automation prototype, and for CBSE Class 11-12 or B.Tech first-year students building a sensor-based control system. The beginner-friendly design makes it a strong mini-project choice for school science exhibitions or personal aquariums.
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.
What if I get stuck during the build?
Scan the QR code inside the box to chat with our AI companion trained on this exact project. If you need human help, WhatsApp our Bengaluru support team for step-by-step guidance.
Is soldering safe for younger builders?
We include a standard soldering iron and strongly recommend adult supervision for builders under 12. The PCB prototype board has clearly marked pads to make soldering easier for beginners.
Can this controller be used with a saltwater tank?
Yes. The DS18B20 sensor is waterproof and compatible with both freshwater and marine aquariums. Just ensure the probe is fully submerged and the wiring stays dry.
What if I want to add a pH sensor later?
The Arduino Nano has spare analog and digital pins. The AI companion can guide you through extending the code and wiring to include an additional sensor like a pH module, which can be sourced separately.
DS18B20 water temp and DS3231 schedule control heater relay, light relay and feeding servo.
