Build a Tank Water Level Indicator with Arduino Uno & LCD - Beginner Kit

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 a small circuit on your desk that reacts when you dip sensors into a glass of water and shows the exact fill percentage on a glowing LCD screen. With this kit, you'll build that circuit in under two hours-no soldering, no previous experience needed. It transforms a simple water level curiosity into a digital readout you can understand instantly.

What You'll Build

You'll assemble a working water level monitor that uses five exposed probes to detect water presence at different depths. The LCD screen displays the tank level as a simple percentage, turning vague water levels into a clear, digital reading you can monitor instantly. This hands-on project connects a real-world sensor to a display, laying the foundation for dozens of other monitoring ideas.

What You'll Learn

• How a water level sensor works using conductivity between five probes
• Wiring an I2C LCD backpack to drastically reduce the number of pins used on the Arduino Uno
• Reading analog sensor values with the Arduino Uno and interpreting them in code
• Converting raw sensor readings into a meaningful percentage display on a 16x2 LCD
