The board has 8 leds but i think i'll need 11 to present the 11 bits. Any idea? Or i will make except portD and portB as output? In assembly would be nice. Ihave avr studio to connect with stk500. Thanks Very good job.Im impressed

The other two are data outputs generated by the keyboard when a key is pressed. No data needs to be sent to the keyboard, so the interface is very simple. The two data outputs from the keyboard are clock and data, both normally high. When a key is pressed, the clock signal pulses low 11 times, and the data signal sends 11 bits of data in sync with the clock. Bits 1-8 are the scan code data byte. Bits 0, 9, and 10 are start, parity, and stop bits, and can be ignored. More data details can be found in this write-up of interfacing a PC keyboard to a microcontroller.  [...] [...] It turns out that only four of the pins on the PS/2 connector are used by the keyboard, and two of those are power and ground.

Seriously though, nice write up. I'm looking to do something similar on my Arduino. This will definitely be a source I'm coming back to. Thanks for taking the time to present this. omg, i r total noob. can u pls help me do my projekt? pleas help me.
