Step 3Get Everything Ready: The Arduino Hardware
Okay... if you're going to hook your Arduino up to your cartridge, you're going to have to wire it up. Take a deep breath, find your center and relax. Its easy as can be... and we have pictures. Everyone loves pictures. :-)
NOTE:
My directions are for an Arduino Diecimila, so if you got a different version you may see some slight variations, but its probably nothing you can't figure out by your lonesome. If it is, just drop me a line and I'll help you out.
Picture #1 has us installing an LED. You can use any color you like. You'll jam the legs of the LED into Digital Pin 13 and GND (fortuitously situated next to each other) but first check the polarity! The bottom of your LED will have a flat edge. The pin on that edge needs to go into GND.
If you get it backwards, it will never light up. NEVER! Mwuhahaha...... Of course, you could always just turn it around. That might work.
I'm okay now. As I was saying....
We've got our indicator hooked up (cake, wasn't it?), now we just need to connect to the cartridge.
The chip on the cartridge has four contacts. I know, I know - it looks like there are eleven, but trust me... there are only four. Eleven little gold contacts connected to four wires: power, ground, clock and data, so four contacts. These equate to pins 3V3, Gnd, A4 & A5 on the Arduino. These are all on the oppsite edge of the board from the LED - if you want to make it easier on yourself you can use black, white, blue and green wires as I have done here in picture 2.
