GPIO

This package provides drivers for General Purpose Input/Output (GPIO) devices. It is normally used by connecting an adaptor such as firmata that supports the needed interfaces for GPIO devices.

Getting Started

Installing

go get -d -u gobot.io/x/gobot/...

Hardware Support

Gobot has a extensible system for connecting to hardware devices. The following GPIO devices are currently supported: - Button - Buzzer - Direct Pin - Grove Button - Grove Buzzer - Grove LED - Grove Magnetic Switch - Grove Relay - Grove Touch Sensor - LED - Makey Button - Motor - Proximity Infra Red (PIR) Motion Sensor - Relay - RGB LED - Servo - Stepper Motor - TM1638 LED Controller

More drivers are coming soon...

Documentation

Overview
