Hi im a beginner with Arduino and need a SIMPLE diagram of how to set this up please for an art project for someone.
I have an Arduino Duemilanove and a 12 volt car screen washer water pump.
The idea is to fill up a tray with water then the pump switches off to let the water drain away and then to switch on again etc.
I need to pump water from the reservoir for say 5 seconds then stop for say 10 seconds but this would have to be changeable to suit the flow pressure.
I have the basic blinking led light and thought it would be easy to do using those parameters that control the led speed. But not so as I realise now.
Can anyone tell me a simple way to do this with pictures please lol.
Many thanks
Andye
