Here we are with another project log, so, after run some test with my working water pump and some minor tuning on the APP I start to looking for a couple of nice and reliable water solenoids in order to control where the water is flowing. In this way I can virtually manage all the pots I need to water, at the moment to keep the costs low I got my hands on a couple of 12v Water Solenoid valves.

As I am located in Italy I couldn't find the exact model I bought and I don't know in wich country they are available and in wich country they aren't , but, any kind and variant of those

will do the work.

Then I needed to double the size of my two channel relay, so I bought one with 4 channel, something like this one:

They should arrive tomorrow, so in the meantime I started to drawn a simple fritzing schema of the wiring:

I know it's a bit messy, but it's just to give a rough idea on how the connections and the wiring should be made. If anyone has got any questions just ask ;)

See you on the next LOG!
