-Every project nowadays reaches for nice user interface. The display models from the company Nextion are quite famous due to their price and capabilities. The connection is made by a 3.3 V UART interface, either by a USB-TTL 3.3 V adapter or via the RasPi's onboard UART, if not already used. The software is written in Pyhton can can be found here.

+{{::icons:warning.png?direct |}}{{ :icons:warning.png?direct|}}Remember: In the default raspbian image, on Raspberry Pi 3B and Raspberry Pi 3B+, the internal Bluetooth is connected to the internal UART. So as it is quite likely you won't use the Bluetooth, disable it by adding a line
+<code>dtoverlay=pi3-disable-bt</code> to ''/boot/config.txt'' and disable the Bluetooth service with
+<code>sudo systemctl disable hciuart</code>
+Also free the UART from the kernel messages by removing
+<code>console=serial0,115200</code> from ''/boot/cmdline.txt'' and enable the UART by adding
+<code>enable_uart=1</code> to ''/boot/config.txt''
+Further information is just one google search away: [[https://www.raspberrypi.org/documentation/configuration/uart.md|one google search away]].
+Reboot your Pi after doing these actions.
