You can power up the Nextion display directly from the Arduino 5V pin, but it is not recommended. Here’s how you should wire the Nextion display: Nextion These pins are labeled at the back of your display, as shown in the figure below. You just need to make four connections: GND, RX, TX, and +5V. Wiring Nextion Display to the ArduinoĬonnecting the Nextion display to the Arduino is very straightforward. Now, you are ready to start experimenting with the Nextion display with Arduino UNO. Change line 37, so that you have the following: #define nexSerial Serial Comment line 32: //#define dbSerial Serialĥ. Comment line 27, so that it stays as follows: //#define DEBUG_SERIAL_ENABLEĤ. There should be a NexConfig.h file – open that file.ģ. Open the ITEADLIB_Arduino_Nextion folderĢ. To make it work for Arduino Uno, you need to do the following:ġ. This library is configured for Arduino MEGA2560 by default. ![]()
