Yanny or Laurel robot #yannyorlaurel @adafruit #adafruit #CRICKIT


Yanny or Laurel robot (video), we had about 1 more hour before this meme expires, so we made a voting bot, it says the word, logs to csv, moves head, has clickable, light up buttons, it’s a voting machine.. Made with Adafruit CRICKIT, code is here.


# CircuitPython 3.0 CRICKIT demo

    fp.write(selection+", 1\n")

    fp.flush()
