Hello Fernando ,
Some short comments on the pictures of my Ferduino.
Stamps box
Inside of the box
Finished box
Dosing pumps box made from electrical trunking
All pumps installed
Box finished
Relays 1 box
For this, I used 2 multiple outlet modified so that each outlet is independent and controlled by relay( except one which is always powered ).
Here the 2 multiple outlet fixed in the box
In the second half of the box,I fixed the relays board and the step down converter used to power the relays and the 6v outlet for the ATO pump.
Hot wire for the relays
Hot wire installed
Just before closing the box with everything connected
Box finished
