Megaman Blaster Lighted

This is a working lighted blaster for costume/cosplay purposes. I designed this for my sons Halloween costume drawing inspiration from the Megaman cartoon/game. While the blaster is in the color scheme of Protoman, you can easily change the colors to whatever you'd like in Bambu Studio using either the project filament tool or the painting tool. I recommend printing in PETG for added strength but PLA will work just fine. This uses an Arduino nano to control the lights. One long press and release (1 second or more) activates the lights in a forward cascade like capacitors are charging. Pressing the button inside the blaster activates the front emitter and the side lights giving the impression of the blaster firing. A second long press and release deactivates the lights and does a reverse cascade which is slower than the forward cascade, like capacitors that are discharging. The entire system runs on 9 LEDs and 4 AA batteries though any sufficiently portable power source could be used. T
