hello there,i have an arduino uno and would like to plug an audio speaker (5W -not 0.5W- 8 ohm).would anyone have the kindness to tell me what resistor should i use for it? (and explain the calculation behind it so i won't bother again ;P) as a note i've already checked the "arduino tutorial tone". but got scared trying since the wattage of the speaker wasn't revealed...(or does it make sense or matter?)
