hi!
my team is trying to build a custom button panel to control our robot, and we have some questions:
- i have read somewhere that the button panel is made of some kind of I/O microcontroller with buttons connected to it. is there a specific one we must use? because we have a microcontroller in our lab (i can't remember his name) which can be used as HID.
- how do we make our program to "read" this kind of input? (we use java)

thanks in advance!
