Jameco Electronics Magic Color User manual

Magic Color
PART NO. 2193838
Magic color is a guessing game. With this game you can surprise your friends and leave them with amazement, how the game
guesses what they have in their minds. Only two selections require from the user to guess the game the color combination that is in
his mind. The game has the following parts:
1.Matrix rgb board with five rows and five columns of leds.
2.6 buttons. One button is to starting a new game and the other five is to playing the game. Its button (the group of five buttons) is
under a specific column of the matrix board. So under the first column of matrix board exists one button, under the second column of
matrix board exists one button e.t.c.
I will describe the operation of the game in the following steps:
1.The user presses the starting button and leds on the matrix board take different colors combinations between them. For example, a
led can be fixed in red or red color with green that toggle.
2.The user memorizes one led with the combination of color.
3.The user presses the button of a column in which exists the memorized led.
4. The firmware calculates and changes all the places of colors combinations with respect of specific algorithm.
5.Revision of step 3.
6. Finally the firmware guesses the memorized selected combination color of the
user by making all leds to light with this same color combination.

Step 1 - Make sure you have everything you need
Make sure you have all the materials included in the package and all the required tools. The photo is indicative and not showing all
the necessary tools and materials.
Step 2 - Guide to construction
Use the schematic diagram to build your board. *** Please see kit schematics print-out ***
(http://www.jameco.com/Jameco/Products/ProdDS/2193838Schematic.pdf)
Step 3 - Making of the supply circuit
Place on the circuit board components that constitute the power circuit of the game. Follow the schematic diagram and solder the
parts together (D1,R73,R74,C2,C13,IC22,Q1 ).

Step 4 - Place I.C sockets
For your convenience place all the I.C sockets as in the picture.Make sure there is space required between the sockets.
Step 5 - Separate the resistors for driving RGB LEDs
An easy way to separate the resistors 100 Ohm, 150 Ohm is the number of pieces (50 pieces 100 Ohm, 25 pieces 150 Ohm).
Step 6 - Place RGB resistors
Place resistors having guide schematic diagram and photograph.
Step 7 - Place 0.1uf capacitors for shift registers
Place 0.1uf capacitors next to each 16pin socket as the picture.

Step 8 - Place 0.1uf capacitor for micro-controller
Follow the schematic diagram and place the 0.1uf capacitor next to the supply pins of micro-controller as in the picture.
Step 9 - Make necessary connections
Follow the schematic and make connections. Use flexible wires (cut the cable Ribbon 10 Conductor) for the difficult connections.
Step 10 - Separate 4 flexible wires for RGB leds
Use a cutter to separate four wires of cable Ribbon 10 Conductor. Make 25 pieces with length from step #11.

Step 11 - Calculate the length of four flexible wires
Use the ruler to build 25 pieces (each 4 wires). The length to become based on of photography (mm).
Step 12 - Separate each 4 flexible wire
Use a cutter to separate each 4 flexible wire. Make the same for 25 pieces that are made from step 11,10.
Step 13 - 100 pieces of heat shrink tubing (for 25 RGB leds)
Use cutter and ruler to create 100 pieces of heat shrink tubing. Use the length shown in the photo(mm).
Step 14 - Mark the wires
Mark one of the four wires with a marker to be recognized later (Corresponds to the first pin of each RGB led). Mark all 25 pieces.

Step 15 - Prepare the wires
Fit the heat shrink tubing in each wire and prepare the wires with little tin.
Step 16 - Solder the RGB led
Solder every wire from #step 15 with RGB led pins.
Step 17 - Insulate RGB led pins
Warm the heat shrink tubing with lighter. Once you have already placed over the pins.
Step 18 - Connect every led to board
Follow the schematic diagram in conjunction with the pins of led (1.BLUE,2.COMMON,3.RED,4.GREEN). Take a look at the data
sheet in address http://www.jameco.com/Jameco/Products/ProdDS/2128500.pdf and use the marked wire (#step14).

Step 19 - Make wires for buttons
Use the ruler and cutter to build 6 pieces (each 2 wires). The length to become based on of photography (mm).
Step 20 - Preparing 6 buttons
Fit the heat shrink tubing in each wire and prepare the wires with little tin. Solder the buttons with wires.
Step 21 - Insulate buttons
Warm with lighter the heat shrink tubing once you have already placed over the pins.
Step 22 - Connect 6 buttons to the board
Follow the schematic diagram.
Step 23 - Connect the switch and battery holder
Follow the schematic diagram.

Step 25 - Prepare the box
Step 24 - Check
Checking the basics of the board like: there is no short circuit, connections between the IC etc.
Use your ruler and marker to identify the points that will open holes (25 holes led, 6 button holes, 1 switch hole)
Step 26 - Open the holes
Try to keep your hand steady when drilling.

Step 27 - Put round clips
Insert the clips into the holes opened. If a clip does not fit, scratch the interior of the hole with a sharp object.
Step 28 - Glue the buttons
Use a hot glue gun to glue 6 buttons.
Step 29 - Finalize the construction
Place, all led to the clips, the main switch and optional labels
Step 30 - How to play the game
Follow the steps described on the photo to play the game.

Step 31 - General photo of Magic Color
