A JavaScript Robotics and IoT programming framework based on the Firmata protocol for Arduino and other platforms.
Johnny-Five is a JavaScript Robotics and IoT programming framework that allows developers to control hardware like Arduino, Raspberry Pi, and other microcontrollers using Node.js. It solves the problem of programming physical devices with JavaScript by providing a consistent, cross-platform API based on the Firmata protocol, enabling everything from blinking LEDs to building complex robots.
JavaScript developers, hobbyists, educators, and IoT enthusiasts who want to program robotics and hardware projects using Node.js without needing deep low-level hardware knowledge.
Developers choose Johnny-Five for its extensive cross-platform support, robust and composable APIs, and large collection of examples and community resources, making it the go-to JavaScript framework for hardware programming and IoT projects.
JavaScript Robotics and IoT programming framework, developed at Bocoup.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Works with Arduino, Raspberry Pi, BeagleBone, and many other boards, as listed in the supported hardware section of the README, enabling consistent development across platforms.
Includes over 360 example programs with code and wiring diagrams, accelerating learning and prototyping, as detailed in the examples extract.
Provides robust, reality-tested APIs for components like LEDs, servos, and sensors, ensuring consistent behavior, which is a core philosophy stated in the README.
Integrates with popular libraries like Express.js and Socket.io, and IoT frameworks like Octoblu, as mentioned in the README, enhancing project flexibility.
Requires flashing StandardFirmataPlus firmware on Arduino boards, adding setup complexity and potentially limiting access to advanced hardware features without custom IO plugins.
Node.js and JavaScript may introduce latency, making it less suitable for high-frequency, low-latency robotics tasks compared to native languages like C or Python.
Despite the abstraction, users must understand electronics and wiring, as evidenced by the detailed breadboard diagrams, which can be daunting for pure software developers.
