# 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 [<mark style="color:purple;">Arduino Nano Every Relay Shield</mark>](https://www.brlabelectronics.com/product/ArduinoNanoEveryRelayShield/13?cp=true\&sa=true\&sbp=false\&q=false)
* The Nextion Editor - Download and install the latest one [<mark style="color:purple;">here.</mark>](https://nextion.tech/nextion-editor/)
* The Arduino IDE
