Bubble Level

Turn your AMOLED into a precision spirit level. Hold it sideways for the classic horizontal tube, upright for plumb checks, or flat for a 2D bull's-eye level. Bubble physics, tilt readout, and color feedback are driven by the QMI8658 accelerometer at 20 Hz.

Controls

• BOOT — cycle horizontal / vertical / flat
• PWR — zero the current orientation
