So I have a macbook pro and wanted to use my arduino to control it.
I took the back off and I have hooked up the arduino power pin to the macbook power supply, all of the digital pins to the motherboard and I've even tried glueing the analog pins to it too but I'm still not getting anything?!
I was told to connect to the serial port so I did and I get no output even when I press all of my keys.
Could it be because I didn't connect the ground to anything?
