Seeking cheap 4x4 keyapd
I am new to interacting with hardware and am looking for a 4x4 keypad which is cheep and simple to connect & read from.
I am UK based, so a UK supplier is preferable. I probably need detailed instructions on how to connect it
Thanks very much for your help.
The thing is, I have no idea about GPIO pins & such - do you know how I can find out how to connect it to the Omega 2?
