During the week 5
class, the group started off by soldering four wires onto the matrix driver.
The group worked together to solder, one member doing two wires and the other
two members each soldering one. These four wires allow the joystick to be
connected. The connections can be shown in figure 1 and 2 below.

The red wire connects to 5V, the black wire to ground, the blue wire to the third analog port (A3) for the x potentiometer, and the fifth analog port (A5) for the joystick button.
The group also
worked on the program this week. As of the end of the week 5 class, the connect
four game is playable, but the program does not yet recognize the winner of the
game. It starts off with a blue light in the upper left corner, which moves left/right
depending on player 1's movement of the joystick. When the button is pressed,
the blue light cascades down the column to the last available space. Then it
switches colors to red and does the same thing for player 2's turn. Eventually
the program will be able to recognize when one of the players connects four of
their color in a row. Figure 3 below shows a sample game, where player 1 (blue)
has won (on the diagonal).
