Hey all I'm sure that these questions have been asked before, however here goes... So I'm in the process of building a sentry gun for a paintball gun... I have been on the sentry gun website and have asked but not gotten any answers I can use. I have a board controlling the gun itself with a micro switch that I can tap into, allowing me to keep the marker as a whole unit and able to use outside of the sentry when I want to. I was looking at a motor/servo shield to make wiring the servos a tad easier, can I also use that same shield to operate the marker?
