project: desktop volume control with Arduino
I totally get the need for an emergency stop button for music. And using a mouse to drag the volume up or down is one of the worst creations of this age.
This device uses the odd fact that this Arduino can send a keystroke to your computer – ‘it has a keyboard emulator’. You might customise the project for movie editing. Use the turn action to tweak the playhead position and use a press to split the track. If you use an app for music editing, GarageBand or drawing, track control and mode changing may slow you down. And if someone’s selling a high priced gadget to help there, this project makes you one for a few £ or $.
Credit for this idea goes to Josef Prusa of Prusa Research – who make 3D Printers using 3D printers. Extra thanks to Mr Prusa for presenting the project so well as it got me started making crazy stuff.
What you need for this project
- Josef Prusa’s post & video – links below
- Arduino pro micro – with USB “Pro Micro ATmega32U4 5V 16MHz”
- Rotary encoder – not a potentiometer
- A project box or 3D printed case
- Some soldering and mostly female-to-male Dupont wires.
