I just realized that you can use any organic material to touch and control your touch screen devices. So, I made a simple smartphone screen touching machine. Let's see...
Detail
1. First of all, find these materials :
- Arduino Board
- Icecream sticks
- Many rubber bands
- Organic material -> Red Onion
2. Next making machine like this
3. Write the code for servo sweep. You can find the code on Sweep example from Arduino IDE.
4. Download the code. Place your smartphone under the red onion and turn on the machine.
5. Here is the working machine video clip. Enjoy !!
