−
−	* if getting the error "avrdude: stk500_getsync(): not in sync: resp=0x49" then take pin out of rx on receiver when uploading sketch
−	* VCC FROM SENDER AND RECEIVER DO NOT NEED TO BE CONNECTED ONLY THE GND OF BOTH SHOULD BE CONNECTED!!!!
−	* in Arduino: Command-T to autoformat
−	* in Arduino: Command-C over highlighted text to comment it out
