GPIO

This package provides drivers for General Purpose Input/Output (GPIO) devices . It is normally not used directly, but instead is registered by an adaptor such as firmata that supports the needed interfaces for GPIO devices.

Getting Started

Installing

go get github.com/hybridgroup/gobot && go install github.com/hybridgroup/gobot/platforms/gpio

Hardware Support

Gobot has a extensible system for connecting to hardware devices. The following GPIO devices are currently supported:

• Analog Sensor
• Button
• Direct Pin
• LED
• Makey Button
• Motor
• Servo

More drivers are coming soon...
