Using this board, we will assemble the circuit.
This build makes heavy use of soldering, so check out the soldering wiki page: INSERT

To start off, let's solder the resistors. There are 3 resistor values used on the board; 10,000 ohms (10K), 1,000 ohms (1K), and 560 ohms (560).
The resistor values are coded by colored stripes on the side of the resistor; the following chart describes this code:

To solder the resistors, first bend the legs over, and thread the wires through the holes in the board.

on the back, bend them out a little to hold it in place, and then solder the connections.

Then, clip the leads back to the top of the solder joint
