I am building a pop up for inside a coffin that is pneumatic. Having the guy pop up is not the problem since I am buying a kit that will do that and will control it is a picoBoo and a kit I am buying. Now what I am wanting to do is have his head turn from a laying position turn the the crowd when it pops up. I am thinking this has to be done with a servo correct or can this be done with a wiper motor. A wiper motor would make it go all the way from left to right and not what I am wanting. If I use a servo how would I program the action for him to turn his head? Would I need to use VSA or is there a way I can do this with the picoBoo?
