This short video is a tutorial on how to use an Arduino as a USB to TTL (also known as COM or RS-232) converter. I was using a dedicated converter bought from eBay in my previous video: youtube.com/watch?v=IHNrnLnLakE. If you have an Arduino lying around, it will easily substitute a USB to TTL converter.
