The ATir is an interface device to emulate the function of a PC “AT” keyboard and controlled with an infarred (IR) remote control using an “AT”tiny45 microcontroller.

The device hardware is composed of an Atmel™, ATiny45 microcontroller, a Sharp™ infrared receiver / demodulator and a few discreet components consisting of low pass filter components and pull up resistors.

The microcontroller source code was developed in C using AVR GCC in AVR Studio 4 version 4.12 development environment.
