IDUINO for maker’s life Description: This 2.8” TFT Touchscreen is designed to suitable for Arduino UNO/Mega2560. It can directly plug inoto the UNO/Mega2560 board without any wiring and soldering. Library is compatible with Adafruit TFT touchscreen shield, which is easy to use . It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

Here we use the phone call to show. Before uploading the code, you need install the library first. And no wire connection is needed, just plug the Screen module on the UNO/Mega board. www.openplatform.
