I am trying to build a prototype using the Infrared transmitter and reciever, and I have two boards that I am using. I am using the Arduino Web Editor and two Arduino Uno R3 boards from a vendor called Elegoo on Amazon. I can verify and save my sketches online, but I am having trouble uploading it to the board. I have the board "Arduino/Genuino Uno" selected and a little grey box pops up saying my sketch is linked to the board. I have not selected a port. What do I need to do to be able to upload my code?
Thanks for your help!
