Foot Pedal Keyboard

A foot pedal keyboard, using Korg EC5, Arduino and Python Converts pedal button events into operating system virtual keyboard sequences.

Sample applications

Media editing 📸

Control media editing software, such as Adobe Photosop and Premiere, with your foot

Program code 👨‍💻

Use the foot keyboard pedal to send macros to a code IDE, such as Visual Studio Code

Practicing musical instruments 🎸

Control playback with your foot, without stopping the practice. The hands stay on the instrument (e.g, Bass guitar) and hitting a foot pedal rewinds the playback to the start.

Using with Practice#

For example: If Pedal A is clicked (pressed and released) then the python driver will generate a Media Prev keyboard stroke on the operating system. A musician can then control music playback by using his/her feet, a very natural way for musicians that use foot pedals for effects and volume control, when playing instruments such as guitar, bass guitar and keyboards.

Originally, I wanted to be able to able to control Practice#, my open source practice application, with my feet - instead of getting out of practice position and having to use my hands in order control the application With Practice# the setup is as followes:

  • Pedal A -> Look back (key = l)
  • Pedal B -> Rewind a few seconds back (key = ,)
  • Pedal C -> Toggle Play / Pause (key = space)
  • Pedal D -> Slow down (key = s)
  • Pedal E -> Speed up (key = f)

But I decided to make a more generic solution. The python driver supoorts dynamic supports any desktop application through an easy to configure json file (key-mappings.json). The default configuration file contains Chrome mappings - a tab can be closed with Pedal E!

Video games

A foot keyboard can provide extra keys to use in games such as first person shooters (FPS). For example: Pedal A could be assigned to a crouch action, or to a series of keyboard actions that would be executed in sequence
