To interface with 5V logic, pins 2,6 and 7 need to have a resistive voltage divider to reduce 5V to 3.3V. You can use an 820 ohm series resistor and 1.2K resistor to ground to do this. 820 ohm ...

The following is an easy way to get started: Take a PS/2 mouse apart without cutting any cables. Desolder the socket that the PS/2 cable is connected to. Use a multimeter to find the pinout of the ...
