I have a 6 inch TFT LCD screen in my hand, I plan to use it to see the reference design while doing graphic design, but there is only rca input. Is it possible to make an Arduino based converter
I believe RCA is analog so probably not.

What is your technical skill level?
I don't understand what you mean as technical capability, sorry. I want to read VGA from analog pins and output via rca from digital pins, but I couldn't find any source. I think it has such a capacity as it can output images for Arduino vga and rca.
vga is also an analog video transmission format
Thank you for the video, now I have a few more ideas in my head
RCA is not a video system . It mean a connector type. Generally used for CVBS = Composite Video (NTSC or PAL) Scanning are 525 or 626 lines vertical resolution. It is interlaced with 30 or 25 fields (odd even) per frame. VGA is also analog splited in Red Green and Blue and Horizontal Sync and Vertical Sync. It is not interlaced and it have have different timings from CVBS.
thank you I know that rca is composite video vga has pins allocated as red green blue hsync vsync When vga has 60 timing, it should be composite 25 or vice versa, I'm wondering how I can convert them to composite video and output as rca. I used translation in most of the sentences, I apologize if I had a rude attitude so that there would be no semantic shift.
Conversion from VGA to CVBS requires a complex circuit. A Google search should show some. But is better to find an ready adapter. It is not expensive.
The device you’re looking for is called an ENCODER, for PAL or NTSC- depending on where you are.
As noted, it’s a fairly complex analog circuit with precise timing and phase consideration.
Quite affordable as a prebuilt module.
I got it. It's not a simple task that can be done with Arduino. Thank you for your help.
thanks
