Tic Tac Toe Game Tutorial
We hope you have friends, because this months kit is a two player game! This is the Tic Tac Toe Soldering Kit. This kit contains exactly what it sounds like-a classic game of Tic Tac Toe. Play with your friends-or lacking those, play against yourself, or perhaps a stranger across the way!
First, you should refresh yourself on soldering safety!
WARNING: SOLDERING IRONS ARE HOT. SOLDERING IRONS ARE NOT TOYS. ALWAYS WEAR EYE PROTECTION WHILE USING A SOLDERING IRON.
Buttons → These momentary buttons create a connection when pressed, and give feedback to the processor.
Count all of your parts and verify everything is in your kit.
Locate the 470 ohm resistors, there should be at least 18. Bend the leads and install into the locations marked R101, R102, R201, R202, R301, R302, R401, R402, R501, R502, R601, R602, R701, R702, R801, R802, R901, and R902.
Locate the 10K ohm resistors, there should be 10. Bend the leads on the resistors and install them into locations R1, R2, R3, R4, R5, R6, R7, R8, R9. and R12.
Locate the 4.7K ohm resistors, there should be 2. Bend the leads on the resistors and install them into locations R10 and R11.
Locate the 28 pin DIP Socket and install it into U2. Be sure to align the notch on one edge of the socket to match the printed notch on the PCB-it should be pointing towards the Nano.
Next, locate and install the buttons in the middle of each "square," at locations SW1, SW2, SW3, SW4, SW5, SW6, SW7, SW8, and SW9.
The red LEDs will install into the corners of each "square," as if to make an X, these locations are marked with the designator D___RED. Be sure you install with the correct orientation and the length of the pin on the diode matches that on the PCB! Locations: D101RED, D102RED, D103RED, D104RED, D201RED, D202RED, D203RED, D204RED, D301RED, D302RED, D303RED, D304RED, D401RED, D402RED, D403RED, D404RED, D501RED, D502RED, D503RED, D504RED, D601RED, D602RED, D603RED, D604RED, D701RED, D702RED, D703RED, D704RED, D801RED, D802RED, D803RED, D804RED, D901RED, D902RED, D903RED, D904RED.
The blue LEDs will install to form a circle around the button, as if to make an O, these locations are marked with the designator D___BLUE. Be sure you install with the correct orientation and the length of the pin on the diode matches that on the PCB! Locations: D105BLUE, D106BLUE, D107BLUE, D108BLUE, D205BLUE, D206BLUE, D207BLUE, D208BLUE, D305BLUE, D306BLUE, D307BLUE, D308BLUE, D405BLUE, D406BLUE, D407BLUE, D408BLUE, D505BLUE, D506BLUE, D507BLUE, D508BLUE, D605BLUE, D606BLUE, D607BLUE, D608BLUE, D705BLUE, D706BLUE, D707BLUE, D708BLUE, D805BLUE, D806BLUE, D807BLUE, D808BLUE, D905BLUE, D906BLUE, D907BLUE, D908BLUE.
Locate the yellow capacitor, this will be installed in C1.
Install the female headers into the PCB, and then plug the male headers into these to create a stack. Finally, slide the Arduino Nano on top of the male pins making sure the USB is facing outward. Solder the corner pins on the Nano first to make it hold, and then flip the entire PCB over and solder the corners on the female headers. Once everything is aligned how you like, solder the rest of the pins.
Bend the leads slightly on the MCP23017, and install it into the socket. Be sure to match the notch with the notch in the socket AND on the PCB. Installing backwards will cause this kit not to function correctly.
Plug in the USB to a power source and have fun! Beat the game by beating your friends! Good luck!
