i thank you a lot, i was looking for this all over the place i actually needed to transfer excel sheet values to arduino, but gave me the idea how it can be done thanks

Thank you sir,
Please create more videos for communication b/w Arduino to Computer.

DISCLAIMER: iT IS NOT usb COMMUNICATION. it IS SERIAL COMMUICATION ONLY BUT USES usb CABLE AND usb PORTS. aURDUINO HAS usb TO SERIAL CONVERTER.

Ok, I don't want to be snarking in comments but I have been searching for this information most of the morning, so please excuse the snark. I get that the music is "cool" and all but you could have a blog post and it would take me 30 seconds to see what you are communicating and add it as a reference to boot. Instead, you create 6 minutes of writing a blog post in real time and I get to watch. This kind of information and instruction does not lend itself to this medium. Thank you.

Sir I am working on a Bluetooth project. I want to configure the Bluetooth module using AT commands but without using the serial monitor. I want to send the AT commands through the program itself. Please help me with this stuff.

Hi,
Have you a solution to use usb cnc breakout board without g-code, do you know how we can send order by pc to move axes X, Y, Z and without usb cnc controller software .
Thankyou

i need tcp version this application. how can i use ethernet cable(not usb) to data transfer from pc to arduino.

Good Day Sir.. can U also make something like when U draw on sketch pad for exm then it will output the coordinates in arduino..

Is there a newer version for this code??? i have worked out that val=raw_input is now just val=input but us there a change to ser.write????as im getting an error message

[talhasiddiquixd]

sir can you make a tutorial on how to send data from arduino to python

[NebulaGames]

Great Video but you should talk!! Dont worry about voice or accent.

Hello
How i can receive number from python to arduino for blink led automatically not by input user

Hi Shubham, Nice video. Are you using serial port or USB to connect to Arduino? Thanks.

[julienmaitre]

thank you very much for this video tutorial !!!!

how to use usb transfer file from pc to pc? who can help me ?

[thadeubrito]

I have a question, sometimes we need to install the drive for arduino before use it. I want to create a product where the arduino will be connected by serialport, but it must be ready to play. is it possible?

[m.a.sherif]

Can u do the same but with arduino communicating to ROS or robot operating system

[rasterman]

Good going but you should add Python code to close your port.
ser.close()

[petergamma]

Is it also possible to read data from the Arduino on the PC with this method?
