I want to modify the Smart Garden System to control a 12v water solenoid instead of the pump. The SGS has a USB port to run the pump. I want to attach to the Solenoid/relay instead. Solenoid is 12 Volts while the pump is 5Volts.

Greetings BP! The bad news is we are at least six months away from a hops harvest. The good news is we have 6 months to really mess things up!
Speaking of which here is my progress: charlesdarwall.com/images/solenoid.png It is lovely looking but now I have to plug it into the USB. Arrrrgh! I shall assume the Solenoid positive (red) goes directly to the 12V power source. But the ground. I need to get the power 12 ground through the USB device, without making Raspberry crumble ... Hmmm...That is the great mystery.
