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

Arduino serial communication is a way to send or receive messages from your pc to Arduino through a serial cable connection.
How to talk to your Arduino tutorial will guide you on how you can send or receive messages by using a data cable between your Arduino and Your personal computer or PC. this is a detailed Arduino tutorial.
do visit our website here you will find a lot of interesting Arduino projects such as Arduino Quadcopter, Arduino Real Time Clock, NodeMCU Projects, Internet Controlled Car, etc.

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

[@tamasau8725]

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

[@RoboCircuits]

Thank you

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.

[@RoboCircuits]

Yeah... Watch other videos... I started using mic

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.

[@RoboCircuits]

Yes its possible. You can use serial communication for that

[@jaimealba3178]

Thanks you helped me a lot !

[@RoboCircuits]

Welcome

[@andystewart5864]

You need to revise as this program does not run in the new IDE 2.3.2

[@RoboCircuits]

Sure

[@user-hx2me8bg8e]

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

[@RoboCircuits]

What you think is a better way?

[@ranajoymallik5335]

Serial.parseInt()

[@ProGamer-sv6cz]

Make a keyboard with this plz

[@RoboCircuits]

sure

[@ProGamer-sv6cz]

​@@RoboCircuitspls make a video

[@diateca1330]

Fiend what is the name of the song ?

[@RoboCircuits]

Actually i forgot...

[@Mathocube]

Good

[@RoboCircuits]

Mathocube thanks

[@asgerjrgensen1414]

Say something

[@RoboCircuits]

What?
