It has the following features:\n\n  * Volume control via encoder and Apple remote.\n  * Input selection via Apple remote.\n  * Start-up mute.\n  * Volume fade when powered on.\n  * Volume level memory (EEPROM).\n  * NeoPixel shows volume level with colour.\n\nFull details can be found here:\nhttp://www.diyaudio.com/forums/analog-line-level/254244-building-complete-preamp-arduino-remote-volume-input-control.html\n\n## Hardware\n\n  * DAC8812: Controlled via SPI. This is the digital attenuator and controls the volume.\n  * MCP23S08: Controlled via SPI. For the input selector and mute.\n  * NeoPixel: Controlled via a single-wire control protocol.\n  * IR sensor: Standard 38Khz module.\n\nThe IRremote library is from here:\nhttps://github.com/z3t0/Arduino-IRremote\n\nAdafruit NeoPixel library is from here:\nhttps://github.com/adafruit/Adafruit_NeoPixel\n\n## Photos\n\n![GIF of preamp](http://giant.gfycat.com/SneakyBreakableHyrax.gif)\n\n![Completed preamp 1](../master/images/P8040008.JPG?raw=true)\n\n![Completed preamp 2](../master/images/P8040016.JPG?raw=true)\n\n![Completed preamp 3](../master/images/P8040071.JPG?raw=true)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffuturesharks%2Fpreamp-v1","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffuturesharks%2Fpreamp-v1","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffuturesharks%2Fpreamp-v1/lists"}
