I am using a 38kHz IR emitter, I've taken out the IR receivers on these guns and experimented to see if I am able to transmit a signal, it's working fine, however when I connect the IR sensor back in, the hit is not registered unless it's from another gun's ir transmitter. So I believe I need to send an encoded IR signal. I tried to do a sweep of 4,8,12 digit Hex values, it might be longer hex value, and plus its a pretty unreliable strategy so far, because the IR receiver goes off at some random times, and it's hard to see if the hex values was right or maybe the lower bits of the hexvalue is what mattered and things like that. Is there another way I can go about trying to figure out what encoded signal I need to transmit with my IR emitter to register a hit on this Laser Tag gun with the IR sensor.
The product I am working with, unfortunately I can't show you the internal circuitry of this device just yet, if its needed I can do so on my next visit to class. Other than that, here is also another helpful circuit for a basic IR emitter connected to a clock tuned to 38kHz
Any idea on how to find the encoded signal this gun is putting out or how to send a configuration of signals to trigger a hit on this IR sensor. I have extra IR sensors and IR emitters with the same 38KhZ operating frequency to experiment with.
Also note that when I checked how the Guns emitter looked on our own sensors, it was just one pulse at a specified pulse width. So I tried to just mimic that pulse width back into the IR sensor of the gun, but that didn't also work. So I was also wondering, if it is indeed an encoded signal, then shouldnt I see a number of peaks at a time for one shot, and not just one peak of a certain Pulse width..
