A square IPS LCD display is used to display an analog-style watch face, and time is kept by a DS3231 real-time clock. A pair of small vibration sensors are used to wake the watch when the user ...

DS3231 RTC Library for ESP32 & ESP-IDF This library provides low-level support for interfacing with a DS3231 high-precision real time clock via I2C on an Espressif ESP32 system using the ESP-IDF ...

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and ...

There are only four components: an Arduino Nano, a DS3231 RTC module, a SSD1306 128×64 OLED module, and a momentary pushbutton.
