Step 2SSR Board
Solid State Relay Board
If you like, you can also view full-size copies of my schematic and board.
I started by placing all the components on the board. When I was satisfied with how they were laid out, I started by soldering all the items to the board that didn't need extra wire (basically, everything but the ground from the Arduino and the 120v hot line). I then soldered the common grounds/hot wires. As you can see from the bottom of the board, it looks rather messy.
When finished, I tested each SSR separately by hooking up the 120v power and measuring across the neutral and each switched hot output while I put a 5v source across the Arduino side of the board.
