So now I want to replace this LED with "something" that could give a little electric shock to the user. I saw some projects with pens that work with a piece electric lighters but it works mecanically so I don't think I can adapt it to my project.
I am looking for something not too difficult to get working for a beginner like me (although I want to learn and I will but I will not become an expert quickly). If it doesn't work very well it's not a problem, for now I would like to make a prototype.
Do you have any ideas of feasible solutions ?
