8x8 LED Matrix Driver Game PART 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 or expensive Arduino. The kit includes a speaker for sound effects and 3 tactile push button switches. With the Pong game, two buttons control paddle direction and the third controls the "start game" function. The 8x8 matrix is bright and easy to see in almost all lighting conditions. Even if you have never programmed a controller before, you will be writing your own games in record time with this addictive little platform. The kit is powered by 4 AAA batteries (not included) and requires either an inexpensive USB or homemade Serial cable. To see the prototype for this kit demonstrating the PONG game, please refer to the following YouTube entry: http://www.youtube.com/watch?v=cjk5cuqtw4y&feature=plcp Time Required: 1 day depending on experience Experience Level: Intermediate Required tools and parts: Soldering Iron Diagonal Cutters Needle Nose pliers Programming Cable (helpful) Velcro "Adhesive Backed" Hook and Loop pair material (optional) 8x8 matrix LED Red (MUST FIT A 12 PIN PITCH and be 1.25" and be anode and cathode compatible pinout) 28x2 picaxe microcontroller (You will need a programmer) Bill of Materials: Qty Jameco SKU Component Name 3 155380 3 momentary push buttons 1 324672 20 MHZ ressonator 1 151116 0.1 decoupling capacitor 1 94060 10 uf tantalum capacitors 1 216339 battery holder 1 179039 zener diode 4 2157167 10k resistor 1 691180 22k resistor 1 114412 ic socket 1 2151216 piezo transducer 3volt piezo

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 the circuit 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 the graphic 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 the switch is accessible. This switch serves as your ON/OFF for the kit. The velcro strips can be found in many stores and is usually called "Velcro Hook & Loop" fasteners. Trim the red and black wires from the battery pack for mounting from the backside after you are happy with the velcro fastener attachment. Solder the wires from the side you insert them into using the front side of the circuit board 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 how you 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.
