First I will introduce a hardware we need to do this project.

1. arduino

2. ps2 keyboard

3. ir led tx and rx

4. mbed board platform (WIZwiki-W7500)

And picture show us how to connect the boards and component.

Step 2: PS2 Keyboard Connection

PS2 Keyboard Connection

I need to explain about how to connect PS2Key board and arduino.

But it is more easy to see the below.

You can know all about from below.

Step 3: Software for Arduino

Software for Arduino

Arduino is working receive a key value from ps2 keyboard

And send it to UART for irled communication.

Here we have to connect irled to PWM for 38KHz modulation.

It is very simple.

I used a library of PS2Keyboard and just add a PWM and UART function.

Step 4: Software for WIZwiki-W7500P Platform

Software for WIZwiki-W7500P Platform
Software for WIZwiki-W7500P Platform

mbed source code is more simple.

You can see the picture.

It receive ir led data from UART and send it directly to PC serial.

That is all..

The key of this project is UART IRled.
