Water Tank Level Monitor Pro Kit with Arduino Nano + Ultrasonic
Water Tank Level Monitor Pro Kit: Build an Expressive Robot with Arduino Nano
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a small robot that responds to its environment with facial expressions. Using an ultrasonic distance sensor and a sound sensor, the robot’s two OLED eyes change between happy, surprised, and curious expressions based on how close you are and how loud you clap. It’s a fun introduction to sensor fusion and interactive systems, perfect for school projects or weekend tinkering.
What You'll Build
You'll wire together an Arduino Nano, HC-SR04 ultrasonic rangefinder, a sound detection module, and two 0.96-inch OLED screens to create a tabletop robot companion. The robot displays different eye animations on each screen—wide eyes when you're near, squinting when you're far, excited expressions when it hears a clap. By the end of the build, you’ll have a fully functional, reactive robot that demonstrates how machines can exhibit personality through simple sensor inputs.
What You'll Learn
- Interfacing multiple sensors (ultrasonic, sound) with Arduino Nano
- Reading analog and digital sensor data for real-world input
- Controlling I2C OLED displays using the Adafruit SSD1306 library
- Programming decision logic and basic state machines for interactive behaviors

Who This Kit Is For
This kit is ideal for CBSE Class 11-12 students working on computer science or physics projects, ATL Tinkering Lab innovators, and B.Tech first-year students exploring sensor integration. The build time and skill level make it a perfect fit for Smart India Hackathon prototype demos or a weekend family project. Even absolute beginners can complete it with the guided companion.
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?
Open the AI companion via QR code for instant troubleshooting, or message us on WhatsApp for human support.
Can I use this kit for a water tank level monitoring project?
Yes, the same circuit works for water level sensing. The ultrasonic sensor measures distance; mount it above a tank and the OLEDs can show level instead of expressions. The companion app includes guidance for this adaptation.
Do I need any soldering?
No soldering is required. All connections are made on the included breadboard with jumper wires, making it reusable and safe for beginners.
Is this kit suitable for a school science exhibition?
Absolutely. The expressive robot draws attention, and the clear documentation helps you explain sensor principles and programming logic to judges and visitors.
Tank Monitoring — OLED display on robot shows different face expressions based on proximity and sound input — personality-driven robot interaction.
