# Student Manager

Day 60 of the 100 Days 100 IoT Projects collection. Board: ESP32.

An ESP32 with OLED, LittleFS, and JSON stores and manages student records. Databases on a microcontroller.

## How it works

Student records live as JSON objects in the ESP32's LittleFS filesystem, browsed and edited through an OLED menu. It is a complete create-read-update-delete cycle running on a microcontroller — a database with no server, no cloud, just flash memory.

## What you'll learn

- LittleFS filesystem
- JSON on microcontrollers
- Embedded CRUD design
- On-device data management
