/!\ The pins may not match your display depending on the model, check before making connections or open the display and look at the circuit traces to determine what is what /!\

Tutorial

1. Download and install Arduino IDE
2. On your PC, go to your Documents folder, then Arduino.
3. If a libraries folder exists, rename it to librariesold, so you don’t lose it just in case.
4. Download and extract the libraries folder from libraries.rar and place it in: Documents/arduino
5. Download the psa308simhub folder and place it in Documents/arduino.
6. Open the psa308simhub folder and double-click on psa308simhub.ino
7. Arduino IDE should open.
8. Plug your Arduino into your PC
9. Select the COM port of your Arduino at the top, then the model of your Arduino (e.g., Arduino UNO)
