hi i want to create a useless box like this https://www.youtube.com/watch?v=-PqcCjFaf3I
for creating the box i want to use 2 servos, one for open the "door" and the other for turning of the switch
my question is : how i can make the servo do an "up and down" movement for opening and closing the door of the box?
i found some videos were they use some kind of linkage but i don't understand wich one to buy how i can find these pieces?
sorry for my bad english
