my fourth project for fallout

what is this project

• test out your memory with this memory game!
• this project tests your sequence memory, in having a sequence that increases in length after everytime you get it right
• see how far you can go! how many can you remember in a row

assembly instructions

• print out the pcb and the case, and purchase the components meantioned in the bom
• put the pcb in the case
• put on the lid. then attach the screws mentioned in the BOM to fix the pcb in place.
• flash the firmware to the xiao-esp32 through the arduino ide (via usb)
• keep it plugged into your computer, as that will be the power source!
• try and see how many you can remember!

inspiration for the project

• having played the sequence memory game on human benchark, i wanted to have a physical version of this that i could play with!
• i thought it would be a good way to try and improve my memory as having it in physical form i think makes me more likely to use it.

how it works

• the project will show the seqence of keys 1 by 1, you simply copy these!
• see how many of these you can remember!
• if you have a high score, the project will flash 3 times (this high score is stored on the permanent storage of esp-32 board. (using preferences.h)
• if you press the wrong key, then all leds will flash once, and the sequence will reset, (back to a seqeunce of length 1, then you have to memorize a new sequence)
• keep trying to beat the PB!

how this project was made

• case made using fusion360
• pcb made using kicad
• in the 3d model, the keycaps and cherry-switches were imported as step files from repos on github.

total project cost: $28.53 (however will already have components spare from other projects like cherry mx switches, key caps)
