INTRODUCTION & OBJECTIVES:   I is a simple system, using Arduino to automate the irrigation and watering of small potted plants or crops. This system does the control of soil moisture, doing indications via LEDs and in case of dry soil emitting a alarm beep. In case of dry soil it will activate the irrigation system pumping water for watering plants. The system uses a LCD display to notify all actions that are taking place and a real time clock.     The Theory (from Wikiped...
