Working DHD and SFX for Stargate MK2 Design

DHD_for_Stargate_MK2-v1.0.zip - Wiring Diagrams updated on 01-21-19 This is a DHD that works with Glich's remarkable Stargate Mk2 (https://www.thingiverse.com/thing:1603423). The DHD reads resistance from a 39 button matrix and sends the information to an Arduino Nano inside the DHD. The dialed address is sent to the gate, which will dial it. There are three Arduinos total. The DHD Nano, an Uno with a motor shield and an Uno with an MP3 player Shield. The three Arduinos talk to each other via I2C. The Zip file available here has a pretty good roadmap to making this happen as well as the code and necessary libraries. Please feel free to make this better! The way it works: The gate, in rest mode, cycles the Chevron LEDs through some patterns. When you press the first address symbol on the DHD, the pattern stops and the Ramp light turns on. You will hear the key pressed and the first address LED on the DHD lights up. Press the next 6 addresses and when you have all seven addresses, the big red button lights up. Press that and the gate will start dialing the address you entered, along with the corresponding sound effects. The gate then goes through a series of steps to complete the process.
