A Water Level Detection System measures how full a water tank is (low, medium, high, overflow) instead of only “water present or not”. You can build a simple 4-level indicator using: Arduino Water ...

A fully functional Arduino-based blind stick that enhances mobility and safety with real-time detection of people, obstacles, water, and falls, using a combination of sensors and modular feedback ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
