An educational DIY electronics starter kit designed to teach the fundamentals of liquid level tracking, sensory logic, and visual output programming. Powered by an Arduino UNO R3 compatible development board, this kit uses a parallel-trace water sensor to detect fluid levels, giving users real-time readings on a crisp OLED display screen. Equipped with both visual LED indicators and an acoustic buzzer alarm, it provides an interactive way for beginners, students, and hobbyists to build an automated overflow or dry-tank warning device.

Component List:-

1. 1 × Arduino UNO R3 Compatible Development Board
2. 1 × Water Level Sensor Board (Parallel Analog Trace)
3. 1 × OLED Graphic Display Module (0.96" Screen, I2C Interface)
4. 1 × Buzzer Module (Active Audio Alarm)
5. 4 × Through-Hole LEDs (Set of 4 distinct colors: Red, Green, Yellow, White)
6. 1 × Small Solderless Breadboard for easy circuit assembly
7. 1 × Cell Holder with AA Cells (Batteries included)
8. 1 × Micro Controller Cable (USB-B to USB-A programming lead)
9. 1 Set × Multi-Color Jumper Wires (Flexible interconnect cables)

Features:-

1. Real-Time Visual Telemetry: Outfitted with an I2C OLED graphic display module configured to provide clean, instant textual updates on tank conditions (e.g., "WTR LVL: OK").
2. Multi-Stage Alert Network: Includes both an active piezo buzzer module for immediate acoustic notification and a set of multi-colored LEDs for tiered visual status mapping (Low, Medium, Full, Overflow).
3. Linear Fluid Sensor: Features a lightweight, corrosion-resistant water level sensor board designed to map liquid depth through analog-to-digital voltage variance.
4. Solderless Fast Prototyping: Packaged with a mini breadboard and a flexible jumper wire loom to allow swift, tool-free circuit configuration and experimental adjustments.
5. Independent Battery Power: Includes a dedicated multi-cell AA battery holder to let you deploy your finalized liquid monitoring system away from a desktop PC.
6. Open-Source Architecture: Driven by a versatile Arduino UNO hardware base, making it fully customizable using standard C/C++ scripts or scratch-based block coding interfaces.

Applications:-

1. Classroom STEM activities and middle-to-high school introductory physics/coding laboratories.
2. Building simple automated basement flood warning nodes or household overhead tank overflow alarms.
3. Prototyping mini fluid level indicators for hydroponic reservoirs, indoor plant pots, or pet water bowls.
4. Hands-on practice with analog sensor threshold tuning, I2C display configurations, and basic microcontroller loop coding.
5. Great introductory electronics project for science exhibitions and maker workshops.
