from a computer through serial port all without using a microcontroller.
the link is broken
Well, I can use an arduino board and was demonstrating this to a student using the arduino board however i was stumped by a question as to 'well whats the point in using a computer if you are also using a microcontroller. Isn't there some kind of redundancy?'. I think its a valid question and wanted to see if there was a way to do it. So i'm here.
