Hi ,
Wonder if anyone can provide me some inputs on a design to switch sequentially one after another three solenoid valves for plant watering in my garden. I cannot switch all the water lines at one go because the water pressure will drop.
ANy help greatly appreciated.
thanks

A quick solution might be to use a Smart Relay, they are made/relabled by a few Manuf. Idec, Siemens, Omron etc.
The programing is either done through the input buttons on board for simple apps or in some cases the S/W is free.
They also have an on board real time clock for time of day functions.
Max.

Look into lawn watering controllers. Sometimes you can find them very inexpensively (I got one on clearance for less than $5) and they're designed to do exactly what you want.
