Demo mode — replaying real recordings made on an Arduino Uno through the actual
trained model. No hardware needed. It alternates between a balanced fan and one with a
weight taped to a blade, so you should see the verdict flip roughly every ten seconds.

Fault is declared when the smoothed fault score crosses this line, and only clears once it
drops 15 points below it — so a marginal signal can’t flicker.

Reads ax,ay,az straight off the serial port at 115200 baud and runs the Edge Impulse
model in this browser tab — no server, no cloud call. The spectrum is a 256-point FFT of the X axis
with a Hann window, so the tall spike is the fan's rotation frequency and it grows when the rotor is
unbalanced. Verdict is a rolling average of the last 4 predictions, and is sent back down the serial
line as F/H to drive the Uno's onboard LED.
