Help in schematic #2
Comments
Hi soloam,
The transistor is used to drive the IR led (transmit the impulses) as a switch on/off. The led is powered by 5v output of Arduino UNO. In my case for my project I'm using an external 5 volt supply (as output) to drive the IR led and it is enough for me. I've not the right skills to give you the best solution but this is the result of my little experience. So you could wait for the official answer of Danny. Anyway I hope this will help you.

Can You clarify the schematic on the UNO? Part Numbers of the components? Type of led etc.
Thank You
