To give our Arduino the chance to tell sometimes what’s actually going on and do not always use the serial monitor, it is time to buy him a small display. Fortunately, there is a wide range of available shields and breakout boards. In this case, we use a 1.8 inch TFT color display with 128×160 pixels (HY-1.8 SPI, the name on the board), equipped with an SPI interface, which gives us the opportunity compared to displays with parallel interface, to have more free ports for other applications available.

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