Device for touching a touch screen? Answered
I need a type of solenoid/servo device capable of moving a few millimeters at a fast speed. I am building a device that will tap a touchscreen for me via an electric signal (In this case, and arduino.) they need to be relatively cheap and small. I will have four of them evenly spaced over four inches (They need to be no wider than an inch, would much prefer they be less than a half inch in width. Height isn't important, and length should also be under an inch.) They also need to be fairly weak, i dont want one of them punching a hole in my tablets screen by accident. Doesn't need to be controlled by PWM, either off (Not touching) or on (Touching) will work fine.
Please do leave links along with the name of the device/part.
