| Possible commands created in this shetch: | |
| * "/arduino/digital/13" -> digitalRead(13) | |
| * "/arduino/digital/13/1" -> digitalWrite(13, HIGH) | |
| * "/arduino/analog/2/123" -> analogWrite(2, 123) |
To understand some of the pieces, it is helpful to interact with them together. Not sure how this will turn out, but that's part of the fun. Turn the sound up, maybe lock your screen orientation, and check these out:
