I need to build an actuator, arm, robot or something which will press a button for me, I mean on a keyboard, alarm clock, or any other button, hold it pressed for some interval and then let go. I need to be able to configure this interval very precisely, up to 10th of a second. I was thinking of getting an actuator, and interfacing it with some mechanism which will allow me to set the timer very precisely. I am more into computer software than mechanical/electrical engineering, so please bear with me.
Thanks in advance for any replies.
