Hi, I am a real newbie in HW. I started visiting this website and received my first Arduino board a couple of weeks back.
After completing a few tutorials I am now ready for my first project. Basically, I am trying to hack a computer keyboard to simulate certain key presses. I’ve torn a keyboard up and found a tiny board inside. There are a total of 24 pins on the board, 12 on the left and the other 12 on the right. With the keyboard cable plugged into a PC, I can simulate keypresses by connecting a pin from the left side to a pin on the right with a wire. For example, by connecting left pin #3 and right pin #9 the ‘a’ shows up on the PC screen.
What I am looking for is an IC that allows me to programmablely connect pins together. Some google searches led me to something called ‘crossbar switch’. Can anyboard tell me if this is it? I would appreciate if you can also share some information on how to use it too (a link to a sample project would be great).
