Received extra sensors i now have a nice stock of them however i have moved twice since receiving each time not being able to setup my kit so have not yet been able to play.
The concept i was going for is that i split an input from the arduino (an input with attached interrupt) to an i2c expander board so i now have lets say 4 sensors connected to the expander and that connected to a single arduino input.
When a shot is fired at any of the sensors it will trigger the interrupt on the arduino input pin that triggers the routine to decoding the shot packet and detecting from which sensor it recieved the signal from or at least that is the concept.
I suppose what i am trying to do is to multiplex multiple infrared sensors while still knowing which individual sensor the signal is from.
