Hey, This is my first post/ project.
I have just got my hands on an uno board R3 and am looking to use it to control my LED message board.
In order to do this I plan on using the uno to emulate the keyboard of the device. After looking at the circuitry I have worked out that in order to emulate a key press I have to link one of the 8 pins on one side to one of the 7 pins on the other.
E.g A= pin8 and pin15, B= pin8 and pin 14, 3= pin3 and pin10, ect......
So I want to develop it so that pressing the 'A' key on my laptop sends the signal for the Arduino to connect pins 8 and 15.
Is this possible, it seems like it should be, and how do I go about this?
Thanks very much.
