Hi all,
I've just through question in my mind that can I continuously transmit IR signal using IR LED irrespective of what's currently going on in arduino program. I've thought using transistor as a switch with IR LED but that idea won't work. Another idea is that having some external buffer or anything similar that can continuous sending pulses to IR LED and can be turned on or of easily by arduino.
Just want to know whether it is possible or not and if yes then how?
Thanks in advance,
