I have a project in which I am using both IRremote library and NewSoftSerial. It appears that these two libraries have a little trouble working together and I don't know why. Yesterday when I was testing the whole thing there were no problems. Serial communication using newsoftserial worked and I could receive IR remote signals. Later I added a few things to my code and changed some things... and the thing started making problems. I don't have any idea what is wrong but I can't receive any IR codes anymore. A few moments after I restart arduino I still get them but after that no more IR codes are received. If I pull out serial lines and restart arduino I can again receive IR codes. Here is a complete code if anyone has any idea:
