+## FAQ
+- IR does not work right when I use Neopixels (aka WS2811/WS2812/WS2812B)  
+Whether you use the Adafruit Neopixel lib, or FastLED, interrupts get disabled on many lower end CPUs like the basic arduinos. In turn, this stops the IR interrupt handler from running when it needs to. There are some solutions to this on some processors, [see this page from Marc MERLIN](http://marc.merlins.org/perso/arduino/post_2017-04-03_Arduino-328P-Uno-Teensy3_1-ESP8266-ESP32-IR-and-Neopixels.html)

Rafi Khan	d719c27f95	Changed default send pin on ATmega32u4 from 13 to 9 The reason for this change is that I was informed by a community member that the Pro Micro board does not have the default pin 13. This causes many issues for beginners that are not familiar with the inner workings of the library. However, I am concerned about this being a breaking change. If there are serious issues I may just end up adding a tutorial in the FAQ for beginners, informing them how they may change the default pins.	2017-09-14 21:57:01 -04:00
