Arduino Tutorial | Arduino Serial Communication | Send or Receive Message from PC to Arduino

Best training session I have seen. Want to communicate with a car head unit pretending my Arduino is a CD charger.

Make a keyboard with this plz

Another thing I'm lookig for is serial (preerably usb) communication via the digital ports arduino. In a nutshell: I send text from PC to arduino with this USB method and then arduino processes it and sends the result out in its digital ports. On port no 0 and 1 I guess. Is it possible? For instance just simply forward the text I sent on USB.

This is exactly what I searched for. A very basic example. Thanks!

Thanks you helped me a lot !

Fiend what is the name of the song ?

Imagine how much more efficient this video could have been if only you had invested in a microphone, instead of having to type out all of those comments for us to read while being subjected to that obnoxious music. I bet you could have accomplished all of that in less than half of the time, if only you had a microphone. Also, "-48" is not an accurate ASCII to character conversion. Perhaps try not casting characters as integer, and then use something like Serial.print((char) val); instead.

Say something

When you wrote val-1 to obtain the decoded data ,my be this way it's not correct.

Good
