ChronoBloom

The ChronoBloom functions as a smart, internet-connected timepiece driven by a Seeed XIAO ESP32-C3 microcontroller. Upon powering up via a USB-C cable, the microcontroller connects to a local Wi-Fi network to automatically fetch and synchronize precise time data from an online Network Time Protocol (NTP) server. This core processing unit manages three concentric WS2812B individually addressable LED rings containing 60, 24, and 12 pixels respectively. By sending precise data signals via a single-wire control protocol, the ESP32-C3 manipulates the color, brightness, and pattern of each individual LED to visually represent hours, minutes, and seconds, or to display ambient lighting effects. An integrated light sensor continuously measures ambient room illumination, allowing the system to dynamically adjust the LED brightness for optimal viewing comfort in varying lighting conditions. Users interact with the clock primarily through a built-in web server hosted locally on the ESP32-C3, accessed via any standard web browser over Wi-Fi, which enables configuration, time zone adjustments, and trigger settings for focus reminder nudges. Mechanically, the light from the WS2812B rings is diffused and redirected through custom 3D-printed reflector and diffuser components, ensuring an even, glowing aesthetic suitable for a desktop or wall-mounted environment.
