WiFi_IR_Blaster_MKR1000

C/C++
Web server running on MKR1000 that sends IR codes to another MCU via serial
/*
 *  Adapted from NodeMCU/ESP8266 WiFi IR Blaster by Buddy Crotty
 *  
 *  This sketch requires an Arduino MKR1000 for the web server and WiFi portions
 *  and then sends the parsed IR codes to another device that supports the IRremote.h libraries
 *  (like ATtiny85 or Arduino Uno/Nano/Mini) over software serial.
 *  
 *  This works best with another web server acting as a front end that 
 *  sends cURL requests based on which buttons are pressed. 
 *  GET request URL format: http://[ip_address]/[IRcode]
 *  
 *  IR codes can be strung together to create macros 
 *

WiFi_IR_Blaster_Nano

C/C++
IR Blaster code running running on additional MCU (in this case an Arduino Nano). Using the vendor codes rather than Raw IR is much more efficient, but I couldn't get it to work on my appliances.
