## What it is
Cylon.js is a JavaScript/Node.js framework for robotics, physical computing, drones, and IoT. It offers a unified robot definition API with pluggable adaptors and drivers for many hardware platforms like Arduino, Raspberry Pi, and Parrot drones.

## Use cases
- control an arduino with node.js
- blink an led on raspberry pi from javascript
- program a parrot ar drone with node
- read sensors over i2c in javascript
- build a robot with multiple hardware devices
- use leap motion to control servos
- iot projects with node.js

## When to choose
- you want a Node.js framework with a consistent API across many boards and devices
- you need to combine multiple hardware connections (e.g. serial, BLE, wifi) in one robot script
- you like the adaptor/driver plugin model with per-hardware npm modules

## When to avoid
- you need actively maintained software - the last release was in 2020 and many hardware modules are stale
- you need hard real-time control or high-performance robotics
- you prefer Go or Python - the sibling projects Gobot and Artoo may fit better

## Facets
- artifact type: framework
- maturity: maintenance
- function: robotics, iot, embedded, sdk, plugin-system
