This time i ordered a monochrome OLED display with a resolution of 128×64. It works with an I2C interface and needs no background light because of the self illumination type.

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.

As a quasi-nostalgic relic of an almost extinct generation of cell phones we use today, the Nokia 5110 LCD screen from the cellular phone with the same name, kindly as a breakout board for a small budget. Because the display operates at 3.3V, we use it together with a 8MHz clocked Arduino Pro Mini, which also runs at 3.3V.

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.

The LCD display which was originally used in the Nokia 5110 has indeed found a long time ago the way to a breakout board, but it is still simple useful for various microcontroller boards, because it can be relatively easily controlled and programmed.
