# EEPROM Simulator

Day 41 of the 100 Days 100 IoT Projects collection. Board: ESP32.

Emulate persistent EEPROM storage in flash on the ESP32. Save settings across reboots the embedded way.

## How it works

Settings are packed into a reserved region of the ESP32's flash memory and rewritten whenever they change, surviving power cycles just like real EEPROM. Reads are instant from flash; writes are batched to respect the flash's limited write endurance.

## What you'll learn

- Flash wear leveling
- Persistent configuration
- Write endurance limits
- Key-value storage on MCU
