This means each LED lights up when the input voltage increases by a factor of roughly 1.41 (the square root of 2). This is perfect for audio signals, where our ears perceive volume logarithmically.

Updated calculators clearly show you how to change the mode pin (Pin 9) and recalculate total current draw. Older versions often ignored that bar mode requires 10x more current.
