Hands-Free YouTube Foot Controller
Learning a new guitar or piano riff on YouTube, but are annoyed at having to put down your pick and clicking your mouse or keyboard to go back a few seconds?  Now you can control the playback of learning videos with your foot!  Using the FREE “Controls for YouTube” Chrome Insert, you can have your video go back three or five seconds, START/STOP, or fast-forward three or five seconds.  Learn that new guitar part MUCH faster and easier!  Requires a $10 Arduino Pro Micro, five guitar footswitches (about $12), a 5V LED, a USB jack ($12), and about five minutes of soldering.  We supply a Printed Circuit Board to mount the microcontroller with easy-to- solder through holes, the Arduino computer code script, the plastic enclosure .STL file, an instruction manual, and a parts list (with Amazon links) to build it.  All you need is a soldering iron and some solder.
