sACN_intro_pushbutton.ino

/*
  Edited 'sACN intro.ino' for using a push button
  It requires 'arduino_secrets.h'file with SSID and password info.  

   This sketch creates a sACN packet, then uses it to send
   fade information to an sACN receiver.
   This was originally tested with a DMXKing eDMX1 Pro
   and a Coemar LEDko Revlection series spot.
   https://dmxking.com/artnetsacn/edmx1-pro
   http://www.coemar.com/bin/index.php?id=22&serie=2&lng=en&tipologia=1

   Channels used on the LEDko reflection:
   1 - brightness
   2 - red
   3 - green
   4 - blue

   You'll also need to add a tab to your sketch called arduino_secrets.h
   for the SSID and password of the network to which you plan to connect,
   as follows:
   #define SECRET_SSID "ssid"  // fill in your value
  #define SECRET_PASS "password" // fill in your value
