In this tutorial I will show you how to get started with the Arduino Uno Q and how to connect it via serial port using the serial port plugin to UE 5.7.
I will show you how to use the arena level shooter template and using a Blueprint interface connect the ammo to an Arduino 4 digit display.
In the next part I will show you how to connect the Arduino wirelessly to use input devices like the webcam and AI image recognition to control gameplay events.
