I show a few examples of what you can do with a Nextion display and Arduino, and how to do it. For this 1st tutorial I will only send data from Arduino to the display.

Note: On the video I said “microseconds”, but it’s actually milliseconds.

FAQ:
Why I am not using any library?
The official library is too complicated. Sending data without the library it’s actually easier and straight forward.

Why I am not showing how to send data from the nextion display to arduino?
For that, I would have to use the nextion library, and actually it’s easier to send data to the display without the library. The tutorial for sending data from the display to arduino is on my 2nd video of this series.

Why I didn’t connect the blue cable to the Arduino board?
For two reasons: 1st on this tutorial we are not transmitting anything from the Nextion display to the Arduino board so TX on the display can remain disconnected. 2nd the Arduino Nano (and Arduino Uno) only have one serial port that we also use to send the sketch. If you connect the TX blue cable of the display to Arduino RX it’s going to create a conflict and the uploading of the sketch it’s going to fail.

What model is your display?
It’s the 3.5″ enhanced version NX4832K035.
