Electronic valves project

The progect starts with three electronic water valves,a button and the arduino.After the button is pressed the first valve opens for 3 minutes and then closes then the second valve opens for 3 minutes and then closes then the last valve opens for 3 minutes and closes.

So, what's your question? - Scotty

Sounds entirely reasonable - solenoid valves I presume? Any more details?

We do this all the time with our irrigation systems.

You will need a 5v controlled relay (YourDuino.com and others have these) an appropriate solenoid valve (http://www.boxabits.com/index.php?id_product=97&controller=product&id_lang=2 for example) and a power source for the valve via the relay.

Then its simply a matter of connecting the Arduino to the relay and writing the control sketch.
