i made a watering system for my garden. I used a classic 8 relay board to manage the 9v sprikler (bi-stable version).
My wish is to realize a Shield to shrink all the system in a single board.
I would like to know if exist an alternative "object" instead of my "SRD-05VDC-SL-C" because they are too big. What i need is a "switch" (a small solid state relay or an optocoupler) with 5v handler, able to support up to 24v (i am planning to buy a monostable solenoid)
thanks a lot
