Thanks for all your answers, I researched more and found that TSOP output doesn't oscillate. I have looked at datasheet, it doesn't explain anything about it
I want to know about the output of the TSOP1738. As far as I know, its active low pin, and its output is HIGH normally and LOW while Detecting IR, but somewhere I read that its OUTPUT is also oscillating at 38Khz, and we need a RC circuit to convert that output into one pulse, is this TRUE? like...
Its a good information,
Capacitor value should be large enough that it can provide enough voltage(+2 volts means 7v for 7805) to the regulator IC while discharging, means voltage across capacitor should not go below 7v.
I have found two article where Capacitance calculation has been explained...
