I show a few examples on how you can send data from the Nextion display to the Arduino board and vice versa. This time I use the nextion library, but only to receive data from the display. To send data to the display I still prefer sending it without using the library (like I showed on my 1st tutorial), so this tutorial is a mix of both techniques.
Note: On the video I said “microseconds”, but it’s actually milliseconds.
