gollark: Basically, you wanted three levels or something, so store those directly and multiply when actually doing IO.
gollark: (and replace `total -= 254./3.;` accordingly, obviously)
gollark: Make `total` into an int. Replace `total += 254./3.;` with `total = min(2, max(0, total + 1))` or something, if the arduinos' weird language has that. Do `analogWrite(LED, total * 85)`. QED.
gollark: Make the total an integer from 0 to 2 or something and enforce this, then multiply by 85 in the analogWrite bit.
gollark: The main issue is that data is just *data*, and can't corrupt itself in some way if you do stuff wrong or enforce timeouts, only the programs operating on it can (and generally do).
