Built self-watering plant project (by randofo). Can I get help troubleshooting?

Arduino fires up okay, but I can't get the relay to energize, so the pump does nothing, of course.

Great project, but some of the steps aren't clear enough for this retiree. For instance, in Step 23, "Plug the black wire from the circuit board to the ground socket on the Arduino." Which "black wire?"  There is no complete schematic, so I'm guessing at what I'm trying to find.

Also, the Arduino sketch in Step 19 (Randy Sarafan) didn't compile or load into the Arduino until I inserted the missing semicolon after the line
"int dryValue = 700" 

Could sure use some help, as Mama is looking forward to having her vegetable plants watered when we're not home!

Thanks in advance!
