If you ever wanted to automate tapping on a surface or a button for a defined number and with a defined weight and shape this instruction might be of interest for you!
We build this tapping machine to simulate the effect of repeated stylus tapping on different surfaces. How many taps are possible before the material starts to deform or get scratches?
Thanks to the boring socket different stylus and/or tap shapes can be mounted easily.
1.000 automated taps with the tap tap machine
Since the setup is based on a Particle Photon you could also use the machine to link an event from the internet via IFTT or webhook with the physical world ... e.g. by tapping on a physical button or even an Internet button again?
This slightly modified sketch translates a fingertap into a machine tap:
Runs a predefined number of taps (e.g. 1.000) with a predefine frequency automatically (e.g. 2Hz)

Tap Tap Machine
Arduino
Translates a tap of your finger into an automatic tap with with a defined surface, weight & height. Not sure what at this point for what this could be useful for.
