Looking for some advice on how to calibrate a 4-wire resistive touch panel for a BALL & PLATE project I am working on. I do not have a camera to visually do it but i heard there are ways to use an Arduino and and LCD to display x and y coordinates which I can then use to set the calibration point. Any suggestions or advice on how to proceed would be appreciated.
As well on any forums or sites that offer tutorials for Arduino coding. I am new to Arduinos and want to learn how to code so I can complete my project.
Thanks again all
