8x8 LED Matrix Driver GamePART NO. 2171031

This Game Maker II kit is a game design platform using a single color 8x8 matrix LED without the need for a shift register orexpensive Arduino. The kit includes a speaker for sound effects and 3 tactile push button switches. With the Pong game, two buttonscontrol paddle direction and the third controls the "start game" function. The 8x8 matrix is bright and easy to see in almostall lighting conditions. Even if you have never programmed a controller before, you will be writing your own games in record time withthis addictive little platform. The kit is powered by 4 AAA batteries (not included) and requires either an inexpensive USB orhomemade Serial cable. To see the prototype for this kit demonstrating the PONG game, please refer to the following YouTube entry:

Step 1 - Component Identification

1) Verify that the kit contains all the parts shown in the illustration

2) Verify that all parts fit in the holes provided on the circuit board.

Step 2 - Mounting lowest profile parts

1) Bend the resistors as shown in FIG. 7 and mount to the locations shown in the illustration FIG. 6

Step 3 - Mounting next profile height parts

Mount the zener diode shown in FIG. 1 paying close attention to the cathode band end on the diode.

Step 4 - Mounting the 28 pin IC socket

Mount the IC socket as shown in FIG. 5. Pay close attention to the notch in the socket. Match the notched end to the outline on thecircuit board and solder into place.

Step 5 - Mounting the tactile switches and piezo

Mount the Tactile switches shown in FIG. 4. You may need to align the pins on the switches to line up with their holes in the board.Push the switches until they are flush with the board. Do not solder into place without the switches being flush with the circuit board.

Mount the Piezo flush with the circuit board

Step 6 - Mounting the 8x8 Display

Locate pin 1 on the display as illustrated in FIG. 3. The label side on the 8x8 should be facing the switches.

Step 7 - Programming considerations for the GameMakerII

Follow the instructions shown with FIG. 1 to construct a serial cable if that is how you plan to program your kit.

Purchase a USB cable if that is what you need.

Step 8 - Understanding the 8x8 display architecture

Study the graphic supplied in FIG.4. It will help you understand the display better when programming the kit

Step 9 - Understanding Rows and Columns

Understanding the construct of the diodes in the display may help when programming the kit

Step 10 - Understanding the reset switch circuit

The reset button is used in case the processor ever "hangs up" during programming. Follow the instructions that accompany thegraphic shown in FIG. 2 if the processor hangs up. This may never be necessary but it is included if needed.

Step 11 - Mounting the battery for portability

Mount the battery pack as shown in illustration FIG. 3. The Board has been designed to fit the dimension of the 4AAA battery pack.To make your kit portable, attach velcro to the battery pack and to the back of the circuit board. Attach the battery pack such that theswitch is accessible. This switch serves as your ON/OFF for the kit. The velcro strips can be found in many stores and is usuallycalled "Velcro Hook & Loop" fasteners. Trim the red and black wires from the battery pack for mounting from the backside after youare happy with the velcro fastener attachment. Solder the wires from the side you insert them into using the front side of the circuitboard to determine the (+) and (-) holes.

Step 12 - Setting up your serial port and pic type

Follow the instructions shown in the illustration

Step 13 - Setting up your processor type

Follow the directions shown in the illustration. Your Com number will more than likely be different than the one shown but this is howyou will change it by selecting the "Ready for use" line.

Step 14 - Testing the board

A PONG like game is available from the Jameco site along with a short treatise on game construction of your own design.
