# OLED Smart UI

Day 38 of the 100 Days 100 IoT Projects collection. Board: ESP32.

An ESP32 OLED shows animated eyes, the time, and weather in one smart interface. Playful UI design on a 128x64 screen.

## How it works

The ESP32 composes a small interface on the 128x64 OLED: animated eyes drawn frame by frame, the time fetched from NTP, and weather pulled from an online API. Three data sources, one playful screen — a complete lesson in fitting big ideas into tiny displays.

## What you'll learn

- OLED frame animation
- Combining NTP and HTTP APIs
- Tiny-screen UI design
- Multi-source data fusion
