Hey guys, I'm trying to complete this tutorial. I use my Neo as transmitter and my Arduino Uno as receiver. http://www.instructables.com/id/RF-315433-MHz-Transmitter-receiver-Module-and-Ardu/ The first time the compile errors in the virtualWire library i solved by changing (in VirtualWire.h and VirtualWire.cpp) <include wiring.h> to <include Arduino.h> But than the second error appeared with <include util/crc16.h> he can't find the file. Can anyone help me with this problem? I am an absolute beginner so not to difficult please, Thanks!
