How to wire it?

Hi,

How to connect the Arduino to the PS2?

[toncho11]

So

the PS2 cable from the keyboard on pin 3 for CLOCK and pin 4 for DATA (pins on the Arduino).

and the input for the XT computer on pin 2 for CLOCK and pin 5 for DATA (pins on the Arduino).

Hello

Connect:,

Arduino 3 PIN to PS KEYBOARD CLOCK
Arduino 4 PIN to PS KEYBOARD DATA.

Arduino 2 PIN to XT COMPUTER KBD PORT CLOCK
Arduino 5 PIN to XT COMPUTER KBD PORT DATA

Search web for XT KBD PINOUT and PS/2 KEYBOARD PINOUTS.

YES.

Don't forget to connect GND.

Thanks for this quick response.

But there are two grounds ... one that comes from the Arduino and one that comes from the XT computer... So for the PS2 cabel should the Arduino ground and for the connection between the Arduino and the XT cabel should be the XT computer ground, right?

Please put the above pins information (and ground) in the description of your project :). Everyone comes to your project with different knowledge of electronics, Arduino, PS2 and XT computers.

Arduino has two GROUND inputs. So you can use them. One for XT KBD and one for PS/2 keyboard.

Keep informed it will work. I;ts my old project.
