    Supported Hardware

    node-red-contrib-gpio supports several Johnny-Five I/O classes:

    Device IO Plugin
    Arduino/Firmata firmata
    Raspberry Pi raspi-io
    BeagleBone Black, Green, Pocket beaglebone-io
    C.H.I.P. chip-io
    Galileo/Edison galileo-io
    Blend Micro blend-micro-io
    LightBlue Bean bean-io
    ble-io(esp32, curie) ble-io
    Circuit Playground(classic) playground-io
    Electirc Imp imp-io
    Particle(Spark) Core particle-io
    Odroid C2 odroid-io

    Arduino is supported out of the box, but for other devices, you'll need to install their IO plugin.

    For example to install the Raspberry Pi plugin:

    npm install raspi-io
    

    How to use

    Please see the embedded examples.

    Remote Arduino Support

    If you're using Arduino/Firmata, you can connect to a remote device via a raw tcp socket, or an MQTT connection.

    For example, if you wanted to connect using tcp, in node-red you could specify an ip and port. On another machine with an Arduino plugged in you could run a server that relays a tcp socket to a serial port such as: tcpSerialRelay.js

    If you wanted to connect an Arduino to an MQTT server you can use a script such as: bindSerialToMQTT.js. In node-red you can connect to the same MQTT server and subscribe to the topic the arduino is publishing on, while publishing to the topic that the arduino is subscribed to.

    Install

    npm i node-red-contrib-gpio
