Hi everyone,
I would like to use the Capacitive Trackpad/Touchpad - Microcontroller-Friendly PS/2 to measure and save touch pressure data. Since I have no experience in electronics, I am wondering which other parts do I need to order to connect the trackpad to a screen. From the shop I can tell that I would need a PS/2 Keyboard+Mouse to USB adapter, right?
I would highly appreciate your help!

You will need the trackpad, ps/2 adapter and two 10k resistors.

Have you decided what microcontroller you will be using with this?

Thank you for your help. No, I have not decided wihich microcontroller to use. Which would you recommed using if the trackpad is the only device I will be using to measure input force?

Since PS/2 is designed around 5v it might be easiest with a 5v controller like the Metro 328.
