## Health v2 (maintenance only)
Score: 89/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 94, release rhythm 75, longevity 100
- inputs: {"age_days": 2032, "days_push": 37, "days_rel": 85, "gap_med": 69, "n_releases_24m": 8}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
The legacy Arduino IDE 1.x, an open-source desktop development environment for writing, compiling, and uploading sketches to Arduino boards. It is no longer in active development, having been superseded by Arduino IDE 2.x.

## Use cases
- write and upload sketches to an Arduino Uno
- legacy IDE for Arduino 1.8.19
- compile Arduino code for AVR boards
- teach beginners embedded programming with Arduino
- flash firmware to Arduino boards from desktop
- manage Arduino libraries and board packages

## When to choose
- you need the classic 1.x IDE for compatibility with old toolchains or tutorials
- you maintain legacy sketches that depend on IDE 1.x behavior
- you run Windows 7 or an older environment unsupported by IDE 2.x

## When to avoid
- you are starting a new Arduino project - use Arduino IDE 2.x instead
- you need autocomplete, debugging, or modern editor features
- you want an actively developed tool with ongoing bug fixes

## Facets
- artifact type: application
- maturity: maintenance
- function: editor, compiler, developer-tools, embedded
- domain: embedded-systems, developer-tools, hardware, education
- platform: windows, cross-platform
- tags: arduino, ide, legacy, sketches, microcontroller, java, electronics, maker, macos, linux, desktop
