    From inside your node-red directory:

    npm install node-red-contrib-gpio

    Control I/O for Analog, Digital, PWM and Servos

    input output

    Read and Write I2C devices


    Full Johnny-Five script support!


    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.
