Ok folks I have put together the wiring diagram, code and parts list
If you would like the files in a higher resolution email me here and I will send them to you
welshchrisinireland@yahoo.co.uk
I can also send the sound file!
I am in no way a programmer so my code may be a little scrappy, some of it is adapted from a Stormtrooper E11 code used on a different project, there is a section in it for a rotary switch that is no longer being used, I tried to remove it but it seemed to affect the circuit so I just left it in, it doesn't affect the way the rifle operates so use the code as it is or feel free to tinker with it if you wish.
Also there is a slight pause with the sound on the first press of the trigger (no idea why), after that it works fine.
You might want to move the on/off switch to a different position, where I placed mine it was getting knocked off by my glove, I solved it by rewiring the switch in reverse so it gets knocked on rather than off, if that makes sense!
****Important!!!!!, Please be careful when wiring, if you look closely there are basically two power circuits 7.2v from the battery, this powers the led drivers and the Arduino, the rest is powered from the Arduino's 5v output, trigger switch, mp3 player, amplifier chip, dont mix these up or you may very well burn something out!
If anything goes wrong I take no responsibility!
Any questions feel free to ask
