Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

The Arduino Plant Watering System is designed to automatically supply water to your plant's soil once its moisture level falls below a particular point.

The first is an LED matrix that eleven-year-old Daniyal brought to life using Arduino. In the video, he displays each letter of his name on the 8×8 red LED module and then shows his version of ...

I've got an Arduino/Bluetooth (Bluetooth Bee-Standalone). I've hooked it up with an HC-SR04, it's intended to be mounted at the top of a rain barrel to measure the water depth. What's the best ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...

The system has an Arduino commanding an irrigation system based around a pump delivering water from a reservoir. It’s paired with a water level sensor to keep an eye on the water available to ...
