# MicroPython Watch

Day 65 of the 100 Days 100 IoT Projects collection. Board: XIAO.

A XIAO ESP32-S3 with OLED shows time and OpenWeatherMap data on your wrist. Build your own smartwatch face.

## How it works

The XIAO ESP32-S3 wakes on a schedule, fetches time and weather, paints a watch face on its OLED, then sleeps to save battery. A wearable is mostly a power-management problem with a pretty face on top — this build teaches both halves.

## What you'll learn

- Wearable power management
- Watch face UI design
- Scheduled wake cycles
- API-driven watch faces
