Control Relays with the Nextion HMI and Arduino
HomeTutorialsHardware

What You Will Need

These are the basic items you will need to get started:

  • A Nextion HMI - for this tutorial I will be using a 4.3 inch Intelligent series

  • A microSD card that is no larger than 32GB and formatted as FAT32

  • An Arduino Nano Every - I recommend using the Nano Every because you can use 2 serial ports at the same time

  • A relay breakout board or a relay shield - for this tutorial I will be using the Arduino Nano Every Relay Shield

  • The Nextion Editor - Download and install the latest one here.

  • The Arduino IDE
