PASS ONE:
Components:
Four Cables
Arduino
NO code.

I ran a simple through line from Arduino to red cable to green cable to LED to orange cable to yellow cable to ground. I was just excited about getting the LED to light up!

Mistakes: forgot resistor

PASS 2 – Using the Blinkie code.

Added Components:
220Ω Resistor
Arduino code

I added the resistor, after feeling foolish. I will be going back and writing in the code myself (as was suggested by the Resident Help).  I gave the Arduino power, gave it code and…nothing.

Yay resistors! Boo not working!

It refused to light up.  I showed it to a classmate, who had previous Arduino experience. “Why do you have so many cables?” he asked.  We pulled all of the wires out and started over with as little as possible.  This time, it worked.

Mistakes: Not reading instructions, only use what you need.

PASS 3

Added Components:
New Arduino Code – Switch
Two 220Ω Resistors
One 10kΩ Resistor
(Note: I actually used Three 220 resistors, but the issues that arise will unfold in good time.)

For the sake of time, I just copied and pasted the code, at the behest of a friend.  That wasn’t so bright, so I’ll need to go back and do it again, and figure out how it correlates with the hardware.  I decided to go sans switch, in order to simplify the situation and then later I’ll experiment with switch.

The light wasn’t switching very easily.  As it turned out, I used the wrong level resistor, cuz I didn’t read the directions.

But after I continuously rubbed the switch wires together, I  got the 2nd light to turn on and take a picture.

Mistakes: Incorrect resistor.

If anyone would like has any suggestions for how to make this documentation less boring or more effective, please comment! Thanks!
