NEW TUTORIAL: Pro Trinket Rotary Encoder
The Pro Trinket’s USB connector is used for uploading sketches, but the connector is not a full USB port due to lack of dedicated hardware. You can, though, use the connection to emulate some basic USB 1.1 devices via an Arduino software library presented in this tutorial. For example, via the USB 1.1 protocol, you can build low speed USB Human Interface Devices (or HID). Examples of HIDs are keyboards, mice, joysticks, gamepads, etc.
Previous Pro Trinket HID tutorials:
Pro Trinket can emulate a both a computer mouse and keyboard at the same time. The code is a bit larger but adds the functionality of the previous two libraries.
This tutorial will show use of the library using a rotary encoder switch as a digital volume knob and mute switch for multimedia PCs.
