#109 Arduino Basics - Serial Port MEGA VS UNO - Arduino Programming Tutorial

In this tutorial, I discuss the Arduino serial ports. Sometimes you need more than one and both the Mega and the Uno are capable. I mainly use the Mega but this video shows how to convert the code for an Uno.

Thank you for all the wonderful videos, I'm currently using what i've learned from your videos for a product pitch idea.

What does Serial Pin 2 and 3 connect to from the Uno? I have an FTDI adapter on the way and I don’t want to screw it up. My setup is an Uno with the usb connection to a headless pi 4.. I’m attempting to catch what the pi sent over, in a separate serial monitor so I can debug my programming. I know the pi is sending the right byte array but I don’t know what’s happening on the uno end when it’s read

What happens if you use a delay() inside an asynchronous delay?
I have DSbuttons that activate and deactivate some blinkers, but I want to add a button that activates a small blinking secuence on different leds at a difeten frecuency (lets say, blink a certain led three times), I need to be able to activate both functions at any time. I've thought about using a for statement for this, but haven't figured out yet...

Hey I just finish your video thanks for the explanation.
In my case I have a sketch that I run in arduino Mega buuut y need To make the sketch for uploading in ATMega328.

So I need To out (2, 3)

What do you think?Beacuse doesnt work jaja

It is also possible to make single code, compile depending on microcontroller using:

#if defined()
