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 solution comprises an Optomax Digital liquid level switch which is connected to an Arduino board via the TTL output and powered by a 5V source. LEDs on the Arduino can be programmed to indicate if ...

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display, and more.

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove. Aspencore network. ... Insert the 2 probes (wires, pcb) ...

Water Level Sensors, Alexa In A Fish, And Modular Synths During World Create Day. ... The first is an LED matrix that eleven-year-old Daniyal brought to life using Arduino.
