i want a tablet for draw like cintiq but i don't have the money to get it so i can make a tablet like cintiq 
This is an arduino forum.
The arduino is not able to handle large memory intensive tasks like graphics applications.
You can certainly make a simplified, dedicated drawing "tablet" with it along with a compatible touch screen LCD panel, but it doesn't have the horsepower to do any intensive image manipulation.
When I say "simplified" I'm basically talking about like an electronic etch-a-sketch that lets you pick colors. And you could make it save the images to an SD card. It can't handle much more than that. An AVR processor is about on par with a fast 286, but with a lot less memory.
You might want to look at the Teensy 4.0 if you need something more advanced. But yes, an Arduino will get you started with something more basic.
