## What it is
Gaggiuino is an open-source firmware and hardware mod that upgrades a Gaggia Classic espresso machine with microcontroller-based control (STM32 BlackPill/Arduino). It adds features like PID temperature control, shot profiling, and a display while keeping the machine's original look and buttons.

## Use cases
- add PID temperature control to a Gaggia Classic espresso machine
- upgrade a Gaggia Classic Pro with pressure profiling
- build a DIY espresso machine controller with an STM32 BlackPill
- log and visualize espresso shots
- install custom firmware on a coffee machine controller

## When to choose
- you own a Gaggia Classic or Gaggia Classic Pro and want better temperature stability and shot control
- you enjoy DIY electronics projects and want a well-documented, community-supported mod
- you want to keep the stock appearance and buttons of the machine while adding smart control

## When to avoid
- you don't want to open up or modify your espresso machine
- you use a coffee machine other than a Gaggia Classic
- you want a plug-and-play commercial PID solution without soldering or flashing firmware

## Facets
- artifact type: application
- maturity: active
- function: embedded, iot, developer-tools
- domain: hardware, embedded-systems
- platform: embedded, cross-platform
- tags: espresso, gaggia-classic, stm32, arduino, firmware, diy, pid-control, coffee, automation
