How to Send Commands to an Arduino from a Python Script

how can we remove the delay between sending the message and lighting the LED? THANKS

please let know if it posssible to use this in esp32 cam module also

I've looked at dozens of arduino Python tutorials and none of them have worked so it was such a relief to see mine working after I followed yours. Thank you so much!

Cool. I was wondering how I could combine computer vision with an Arduino controlled robotic arm. I thought I'd have to use Raspberry Pi, which isn't capable enough for real-time computer vision. Now I'm thinking of using this method to do the resource intensive action of computer vision on my PC and then just send the coordinates of the detected objects to the Arduino for it to decide how to move the robotic arm.

Your code is fantastic, but if I have to send a NUMBER (also as string) to control a servo motor, how can I change the .ino files to get a string ("0" or"180") and convert to an INT in .ino files? I have seen other videos that use FIRMATA, but the servo has always a bad beahaviour and many delays to reach the position. So I believe that it's better realize a system as yours. Thanks in advance if you can help me

why i can't connect between python and arduino in same com port?

Nice work

Very Nice, Thanks alot

Nice video.
I am automating a power supply by Python with SCPI Commands.
At the same time I need to use Arduino to switch on and off control by Python.
Can I synchronise the two devices - the power supply and the Arduino or, they are automatically synchronised with the PC time?

Hello
I am looking for the equivalent of : arduino.write("X="+str(200)+'\r') in matlab .

there seems to be lagging when input command from pc till the LED is on, is there a way to improve it?

would be great to add your code ! thx
