YouTube can be a brilliant place to learn new tricks, especially in the realm of musical/dance performance and technique. But if we are learning something like guitar, controlling YouTube playback can be a pain because we don't have three hands!

Hence the idea for a foot switch - allowing stop/start, skip and loop control by foot.

The solution I've put together here uses an ESP-12E ESP8266 module. The module interfaces with the foot switch hardware (switches and indicator LEDs), and hosts a web page that plays the video. A bit of Javascript reacts to the hardware state and controls the video.
