Arduino Uno R4 wifi + TF Luma to VVVV

Hi, I’m trying to pass information from Arduino to vvvv beta. I’m having trouble with what to include and syntax. If someone has a simple example of a patch and what the Arduino code needs to include, I’d be grateful.
I’m Serial.print(“string out”) of Arduino and would like to use that to target a jpg and display on the DirectXRenderer or if there’s a better way, please let me know.

Thanks in advance for any and all responses.
