Hello, today im going to tell about uploading the project into Nextion TFT Display via Arduino Uno.
Step 1: Equipment
I have Nextion 4.3" display
Step 2: Connection
you need to connect pins on Nextion and Arduino:
TX -> TX
RX -> RX
5V -> 5V
GND -> GND
Also you need to connect RESET pin on arduino to GND.
Step 3: Nextion Editor
Create Nextion project and push UPLOAD
Step 4: Result
You can see something like this on your Nextion display
