Welcome to Terry's Forums munhann,
You can verify the IR transmitter is working, using a cell phones camera, You should be able to detect and see the IR.
The output going to the 2313 has to be at least 2 wires, Your drawing only shows 1.
You would need a ground return path for that output feeding the 2313 microcontroller.
Or is it on a common power supply ?
Enjoy your project.
