Short version: If I have a computer connected to the USB port, and a Raspberry Pi connected to the serial pins on the board, and I send a message via the Arduino's serial, can it be received by both the PC and the Pi?
I have a project which is a pinewood derby track timer whi.ch presently is configured to send race results via the USB port to a connected computer running race management software. A short video of it is available here:
I also have a raspberry pi instant replay set up which is triggered by one of the Arduino digital pins. Short video available here:
I would like to overlay the race results and the times on the instant replay video as well as send them back to the computer. If I connect the computer to the USB port and the Raspberry Pi to the serial pins, will the data flow through both conduits simultaneously?
Thanks in advance,
