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
