This project is an IR trigger for an Olympus camera. It is able to generate
the infrared (IR) signal to make an Olympus camera focus and take a picture.
The code is written for an ATtiny2313 microcontroller running with an 8MHz
external crystal. It will output the signal on port pin RB0. The IR LED has
to be connected between this pin and ground.

The code in the current configuration will output a "take picture" command
every second. However, this can be changed easily by modifying the main loop.
there is also code to send the "key held" command, but it is currently
commented out. You should treat this code as a building block for your
project or as a proof-of-concept. It is not intended to be market-ready.
