thank you all for the suggestions, i am still going through them
@PeterH & @CrossRoads for proposing the use of a Mega.
referring to (http://www.righto.com/2009/08/multi-protocol-infrared-remote-library.html
Ken Shirriff: "My code won't work with an Arduino mega as it has a different processor and the pins are all different. (Sorry I didn't mention that in my original article.)"
However if sending IR with pin9 of Mega was/is possible, would it make sense to
1) have pin9 connected to multiple IR LED Anodes/+ve legs and
2)the Cathodes/-ve legs of the IR LEDs connected to their own individual digital pin, and control each individual IR LED by switching the corresponding pin "HIGH" or "LOW".?
