One of the best tutorial I have seen in my life. Going right to basics

Thank you for this video. I have been looking at communication between the ESP32 Cam and the Raspberry Pi for future projects. Thanks for getting me started.

Hi Vigasan, please keep product more video, havn't seen you release any new video for year. Your videos are all awesome, we learn a lot from it.

what's a great!! I have one question..
How do you achieve such a short boot time?

[antoninbarta]

Amazing tutorial! Keep posting ! :) Do you have experience with camera control soft? I mean official RPi cams and USB webcams?

[MainzerKaiser]

Great Tutorial. Can you think of any alternative (other micro controller via USB port to RaspPi) to rely only on Python programming? Im a bit anxious about all your code.

Great system,
but i have a question is that. Why don't you use UART protocol on Raspberry (with Uart ports) for communicating between 2 boards instead of using USB port?.
And you have to re-design a frame data to send and receive right?

raspberry pi used a project is protected or not? the example developed one project anyone copes to my project easy access the SD card or not?

[amalsacademy]

Bro how can I run any GUI application in CLI mode on Raspberry Pi..?

[joelkklein]

Do you have a tutorial for install qt in rapsberry.. in my case qml not working

[abneraguila]

Thanks vigasan for the video, I have a question, if I whant to put 4 potenciometer for read, can I put the same sentencie for the others potentiometer ?

[shamikalakshanindrasiri]

Can I know the model of the display in the video ?

[srikanth]

Did you try any gradient in rectangle or images which have gradients and see how it looks on rpi? I am struggling to display basic gradient graphics display properly on rpi. It works fine on windows using QML but not when crosscompiled on rpi.

great lecture!! pls tell me whether Arduino Uno can send images to raspberry pi over serial communication ??
