| Circuit board with resistors soldered on |
Our first task was to solder on some resistors on the board.

| Soldered wires |
Next, I cut off the end of an AC/DC adapter and solder on some other wires to the positive and negative ends of the adapter. I then used shrink wrap to prevent the wires from touching.

| Bread board with LED and 100 ohm resistor |
Using the AC/DC adapter from before, I used it to power an LED on a bread board. However, a resistor must also be used in order to prevent the LED from blowing out.

| Bread board with LED and 470 ohm resistor |
I then used a 470 ohm resistor in the circuit and observed that it light up less dimly.
