Visuals stand out considerably in human-machine communication in projects within the Arduino® ecosystem.
For this communication, input-sensing parts such as buttons and information-outputting elements like screens are used. Using all of these separately can cause a huge mess of cables and pins.
Right at this point, the WaveShare 2.8 Inch Touchscreen LCD Shield for Arduino steps in, allowing you to perform control directly through the interface without needing components like external buttons.
It is a screen shield with a 320x240 resolution and a resistive touch structure that you can use directly with many development boards such as the Arduino® UNO R3 and Arduino® Leonardo.
Thanks to its internal controller, it has a much more sensitive touch detection capability than analog inputs. It has a micro SD card slot on it; so you can easily display pictures from your SD card on the screen.
The screen communicates with your development board using the SPI interface, and its backlight can be adjusted via software through your program.
