AIO

This package provides drivers for Analog Input/Output (AIO) devices. It is normally used by connecting an adaptor such as firmata that supports the needed interfaces for analog 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 AIO devices are currently supported:

• Analog Sensor
• Grove Light Sensor
• Grove Rotary Dial
• Grove Sound Sensor
• Grove Temperature Sensor

More drivers are coming soon...

Documentation

Overview

Package aio provides Gobot drivers for Analog Input/Output devices.

Installing:
