| - | eSafe demonstrates integration of GPIO, interrupts, timers, PWM, and I²C into a user-friendly digital safe. Non-blocking design ensures smooth UI and reliable timekeeping. | + | eSafe showcases the seamless integration of three core microcontroller features: PWM (servo latch), ADC (live VCC monitoring), and I²C (RTC + LCD). All time-sensitive tasks are handled with non-blocking `millis()` logic, so the user interface stays responsive while the clock remains accurate. |
