In my previous blog post titled ‘Arduino/Motor control from variables in UE4 – Part 1‘, I set up an animated object within UE4 and I used the Y positional values to send information to the Arduino to trigger lights at certain positions. Whist this wasn’t too complicated, it was a step towards sending specific values...

So far, I’ve figured out how to read inputs from sensors and controls (buttons) from the Arduino to UE4 (can be found in the blog post titled ‘Arduino to UE4’), and figured out how to trigger the Arduino to execute commands based on UE4 events (can be found in the blog post titled ‘UE4 Event...
