Arduino Controlled Relay Box

Step 2 Assemble the circuit

Assembling the circuit only takes a few steps. I've included pictures of them below and a list of how I built things, which was based upon the height of all the parts.

1. Attach the resistors
2. Attach the diode
3. Attach the transistor
4. Attach the three pin screw terminal
5. Attach the two pin screw terminal
6. Attach the LED
7. Attach the Relay

What I learned while doing this is that it's useful to use the stand to do the smaller parts. When you get to the screw terminals use the table to help you get them on straight. It's difficult to put on the terminals with the LED on the board because it's the tallest compent aside from the relay.
 
Put the relay on last because it gets in the way if you don't.  You will find it to be a little tight against the two pin screw terminal, but that is ok because it still fits.  You don't have to use the two pin screw terminal either and can opt to solder the extension cord directly to the board, but I decided against that for useability.
