# PM_D‑1 Display

A display‑piece metronome — the pendulum is an RGB light bar that combines every lane's subdivisions & accents; a printed tempo scale with a sliding weight sets the tempo.

—
The pendulum is the display: every lane's subdivisions & accents ride along the bar as moving RGB light. Drag the weight up/down (or scroll) to set tempo — the scale is printed on the bar, just like a wind‑up metronome. (No power switch: the real one starts when you lift it from its holder.)
