I am doing project in which I want to perform read and write operation by using a capacitive touchscreen. What I know is I can trigger capacitive touch screen by:
- By using electromagnet as I heard that some of stylus works by using magnet at its point so I think electromagnet should work.
- By using capacitor: If I connect a capacitor's one end to vcc and other to a conductor plate then I think it will mimic the property of human finger and trigger touchscreen.
I want to use these system so I not need to make any physical changes. If I want screen to trigger then I can just charge capacitor or electromagnet. I want to know that whether my theory is correct or not and if there is any suggestion for that then let me know.
