Setting up Pi Zero OTG - The quick way (No USB keyboard, mouse, HDMI monitor needed)

More details - http://blog.gbaman.info/?p=791

For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).
1. Flash Raspbian Jessie full or Raspbian Jessie Lite onto the SD card.
2. Once Raspbian is flashed, open up the boot partition (in Windows Explorer, Finder etc) and add to the bottom of the config.txt file dtoverlay=dwc2 on a new line, then save the file.
3. If using a recent release of Jessie (Dec 2016 onwards), then create a new file simply called ssh in the SD card as well. By default SSH i

// A simple trigger for the Adafruit Audio FX Sound Board
// For complete info on the sound board, see https://learn.adafruit.com/adafruit-audio-fx-sound-board/overview

/*
This is a simple test of a direct trigger of the Audio FX Sounds Board from an Arduino.

For my test, I used an Arduino Pro Mini running at 3.3v & 8mHz. Digital pin #4 of the Arduino
was connected to trigger pin #0 of the Sound Board, and I tied them to a common ground. I powered
Sound Board via a USB external battery for the initial tests, and the Arduino via the FTDI cable.
For later tests, I powered the Sound Board via the Arduino's VCC (3v) pin directly.
