Yes-No Thing

An electronic excise and a table piece made for a themed party. A basic exercise in physical input-output using a servo logic. A breadboard with a servo, joystick, arduino nano, and a usb-to-serial adapter all sitting on a usb charger. A very short arduino code.

  pos = map(pos, 0, 1023, 0, 180);  // rescale joystk value
  myservo.write(pos);               // command the servo
  delay(15);                        // time for servo mvmt
