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 ...

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. ... Insert the 2 probes (wires, pcb) in the dry soil and ...

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.

On Saturday we saw a flood of interesting hacks come to life as more than 100 community organized meetups were held for World Create Day. Thank you to all of the organizers who made these events po… ...
