Hi Nigel,
I started to experiment, just started, with all this.
My questions:
1) As long as I maintain the frequency, is it any reccomended duty cycle?
I believe that if I can go away with 20%, to say something, in the emitted signal, it is better than 80% because my "on" time, being smaller, drains less power from the battery.
2) If for any reason, frequency changes, how forgiving are these IR receivers?
This last is more of curiosity. I plan to work with a 38 KHz receiver module. Last check, 1,4 USD + VAT, here in Argentina. Used to be quite expensive in the past!!
3) The fact of
zeros and
ones taking different times, translates in actual variations of the "instantaneous" frequency. Am I right here? Would you call it "jitter"?
