DAGU Arm Simple Control with KeyBoard

I made a Simple controller for this arm. The controller is based on the Wilde thumper controller from DAGU. It is Arduino based controller with ATMEGA168. For more details about the controller see: https://www.robotshop.com/letsmakerobots/node/24368. Also i used normal PS2 Key board that comes with desktop computers.

I used simple femel-female wire jumpers to connect the PS2 with the controller.

If you need farther information about the PS2 connection and protocol, check this site: http://www.computer-engineering.org/ps2protocol/.
