In order not to have to spend more information on the serial monitor, it is recommended to connect a display. The presented 1.8-inch TFT color display with SPI interface can help here. It has 128×160 pixels and needs in the minimum case, only 4 ports.

1.8 inch TFT color display with SPI interface (HY-1.8 SPI)  and SD card support

It has an LED backlight and can be quickly put into operation due existing libraries for the Arduino. So both texts and graphic forms can be easily represented. Through the SPI interface, the performance is sufficient. Thanks a slot for SD cards, you can even store images and display them.
