.... * Soil Moisure Sensors are responsible for sensing if the soil of irrigated flowers are wet or not. These sensors are attached to the Sensor Controller Module via slow speed I2C bus. The modules use 2-pin probes and drives them with 4 kHz square wave in order to avoid oxidating the probes. In my implementation I used these small water pumps from Conrad: http://www.conrad.hu/conrad.php?name=Products&pid=539090 The whole system is powered by a 12V / 4A SMPS.

This low cost project is a RC servo like position control of one or two geared motor(s) with a pot as angle feedback. You can send the arduino microcontroller a value from 0 to 1023 and the arduino will control the motor speed and direction to reach your target value. The PID algorithm will insure that the motor will not get into hold vibrations if the pot has some influences. This article will describe where you have to take attentions and what you have to setup to get the best results. The project will help you to connect any arduino motor shield or other H-Bridges to the controller because it is open source and the output pins can therefor be changed as you like. ...
