  • why wouldn't that be efficient? You can put an interrupt on an incoming string. Commented Apr 28, 2017 at 15:09

    That use of an Arduino as a 'format converter' to a peripheral from a computer is 'efficient' in the sense that you can use what you have to hand, do it quickly, expect it to work, and debug it easily if it doesn't. It's not efficient in the sense that there's an extra computer in the way, but, who cares? Commented Apr 28, 2017 at 15:33
  • Reading the comments I have to agree with you guys. I like the idea of using an interrupt. I'll definitely check on that and I think that is the solution I might be looking for. Commented Apr 28, 2017 at 17:42
