Experimental DIY Digital Level

Description: A compact, experimental DIY digital level built around an ESP32-C3, MPU-6050, and a 0.96" OLED display. It provides real-time pitch and roll measurements with a clean bubble-style interface, multiple display modes, and adjustable tolerance. The device includes onboard calibration, battery monitoring, and a simple 3-button interface, all designed to fit into a small 3D-printed enclosure. This project is intended for makers who want a customizable, portable digital level and a fun electronics build. Features: Real-time bubble level for instant alignment feedback Multiple display modes (bubble, large pitch, large roll, single axis) Screen color inversion when within tolerance for clear visual feedback Smooth and stable readings using Kalman filtering and averaging Zero button for calibration on any surface Adjustable tolerance (±0.5° to ±5°) Freeze/hold function to lock readings Battery voltage indicator Auto sleep after 30 seconds of inactivity Splash screen with button refe
