How it works

Practice this Arduino feature with a verified Roboda sketch.

  1. Read the constants at the top of the sketch.
  2. Wire the pins exactly as listed in the pin map.
  3. Upload or compile once before changing values.
  4. Change one value at a time and watch Serial Monitor or the output device.
