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.

Time Required: 15-20 Hours depending on experience

Page 3 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.
Page 4 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.
Page 5 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.
Page 6 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.
Page 7 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.
Page 8 Step 24 - Check Checking the basics of the board like: there is no short circuit, connections between the IC etc. Step 25 - Prepare the box 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.
Page 9 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...
