* Pin 5 is the ps2 data pin, pin 6 is the clock pin * Also uses serial protocol to talk back to the host * an Arduino sketch to interface with a ps/2 keyboard. Restart the Arduino IDE, open one of the demo codes, for example ps2_mouse directly by the path:File -> Example ->PS2_Adapter->ps2_kbd.

Download PS2 Adapter library, Unzip and put them in the libraries file of Arduino IDE by the path. Plug the Base Shield into Arduino/Seeeduino and connect Arduino/Seeeduino to PC via a USB cable.ģ. Note: Pin 5 is the mouse data pin, pin 6 is the clock pin. But, don't forget to change the port number in the definition of the demo code at the same time. You can change the digital port as you like. Plug the PS/2 mouse or keyboard to the Grove-PS/2 Adapter, and then connect Grove to the D5/D6 of Grove - Base Shield. Pin 3 is for ground, and pin 4 is for power. Today, this connector has been replaced by USB, but as Arduino/Seeeduino, it is also a good choice to use the PS/2 connector as it is more convenient and cheaper when you need a mouse or keyboard.Ī PS/2 connector has 6 pins as you can see from the following diagram. The PS/2 connector is a 6-pin Mini-DIN connector used for connecting keyboard and mouse to a PC compatible computer system.The PS/2 designs on keyboard and mouse interfaces are electrically similar and employ the same communication protocol. With the help of PS2Keyboard/PS2MouseNlibrary, you can create the bridge between these PS2 device and Arduino/Seeeduino. The PS/2 Adapter enables you to connect a PS2 device to the Arduino/Seeeduino mainboards.
