Good day, I'm Asking help to anyone if it is possible to use TFT touchscreen display (Ili9341) to control 4 relays, then in my relays i will connect a dc motor and led lights thankyou.
Welcome to the forum
Yes, it possible.
You will need to create screen buttons on the touchscreen, see the example
Question, any model and size of tft touchscreen can work?
To make it easier for you, I advise you to choose only those displays for which there are arduino libraries
And of course, the display should have a touchscreen - not all of them have it.
