using an Arduino computing unit I was able to create a feedback system with an IR sensor that produces a small beam when broken outputs a 5volt signal which in return is interpreted as a binary 1. this causes the set countdown on the display to drop by 1 each time the beam is broken, this then happens until the counter reaches either 0 or the magazine is switched out at which point the reset switch is to be activated automatically or manually. A 7 segment display is used to show the number of bullets remaining in the magazine, this can later be swapped out for a liquid crystal display if more information needs to be displayed such as ROF and temperature.
The case in which the unit sits is 3D printed out of PLA for prototyping purposes, made out of 2 main parts, the bottom plate and top cover.
