Now, under Tools - Board, select SparkFun Pro Micro, and under Processor, select ATMega32u4 (5V, 16MHz).
VOLUMELOCK KEY INSTALL
Select and install the package which includes the SparkFun Pro Micro in its list of supported boards. If not, in the Filter box, type Pro Micro.

Check whether Sparkfun Pro Micro is already shown. If you haven't, don't be tempted to try a different one - you'll see why in a moment.Ĭlick on Tools - Board - Board Manager. You will also need to ensure you have the Pro Micro board definition installed. This should give you Extended HID Functions for Arduino. This is easy:Ĭlick on Sketch - Include Library - Manage Libraries. You will need to install the HID-Project library. Now launch the Arduino IDE and locate the sketch VolumeCtrl in your sketchbook. Copy the file VolumeCtrl.ino into this folder. In your Arduino folder (by default under Windows this is in My Documents) create a folder called VolumeCtrl.
VOLUMELOCK KEY DOWNLOAD
If you don't already have it, you need to download and install the Arduino IDE. The optional HID-Project library provides everything you could possibly want. However, amongst those sets there is a huge array of functions defined, though not all are implemented by Windows or other operating systems.ĭigging into it to the point where I was almost ready to start enhancing the Keyboard library, I found it had already been done. In the same way, mouse movements and clicks are another set, supported by the Arduino Mouse library. Multimedia and system keys comprise completely separate sets which are not supported.
VOLUMELOCK KEY PC
I quickly discovered that the Arduino Keyboard library only allows you to send the keys found on the original standard IBM PC keyboard. The existence of multimedia and other keys implies that these too have scan codes, so I reasoned it should be easy enough to program an Arduino to send these since the Leonardo and Pro Micro can emulate a keyboard or mouse through their USB port. The normal alphanumeric and arrow keys don't send a character to the computer but a scan code, representing the key position. Some also have application keys such as email, browser or calculator, and some even have system keys such as sleep and hibernate. You may have noticed that a lot of USB keyboards have multimedia keys such as volume up and down, mute, play/pause. I assume you'll probably use a different box and so I leave most of the mechanical details to you, Other Instructables may give you a more aesthetically pleasing product using computerised manufacturing but my objective is to concentrate on the electronics. Have you ever clicked on a Youtube video and then fumbled for the volume control buttons when it started playing far too loud? Older laptops used to have a physical volume control but this is rare on newer ones and on desktop computers, which is why I wanted to build this.Īnd how many times have you carried on typing long after accidentally hitting Caps Lock, maybe on a scrabble tile type keyboard with the Caps Lock button a bit too close to the A key, and maybe having an inadequate Caps Lock light or no light at all? That was the other reason. Mine implements the volume and mute functions (mute by pressing the knob) and the 3 main keyboard LEDs. Laptop screen brightness (Windows 8/10 only)Īnd many more, subject to support being provided by your operating system.
