Firmata is a serial communication protocol for controlling microcontrollers from software on a host computer, and this repository is the Firmata library/firmware for Arduino and Arduino-compatible boards. Loading the StandardFirmata sketch lets a host computer interact with the board's pins via client libraries in many languages.

Use cases

• control an arduino's pins from python or node on my computer
• read sensor data from a microcontroller into a host application
• blink leds and read analog inputs from a desktop program
• use an arduino as a general-purpose io device without writing firmware
• communicate with arduino over ethernet from a host
• prototype hardware interactions from a high-level language

When to choose

• you want to control an Arduino from a host computer without writing custom firmware
• you need a standard protocol with client libraries in many languages
• you're prototyping physical computing or robotics from a desktop environment

When to avoid

• you need tight real-time performance or fully autonomous on-board logic
• you want minimal firmware size or custom pin behavior baked into the sketch
• you're not using an Arduino-compatible board with serial or ethernet connectivity
