Hello everyone,
I'm pretty new to Arduino programming, and I’m having trouble with serial communication on my Arduino Uno. I’m trying to use Serial. Begin(9600); in my code and have matched the baud rate with the Serial Monitor, but I either get random garbled text or no output at all.
I’ve double-checked the baud rate settings, but I’m still not sure what’s going wrong. Is this something common for beginners? Could I be missing something important in the code or setup? Any help on how to troubleshoot this would be really appreciated!

Well usually, people forget to add the serial.begin() command inside the void setup. Since you’ve already matched the baud rate in your code and Serial Monitor, here are a few things to double-check:
- Double-check you’re using the correct COM port in the Arduino IDE under
Tools > Port. If it's wrong, it’ll seem like nothing is happening. - Make sure you’re not using pins 0 (RX) and 1 (TX) for something else since they’re used for serial communication with your computer.
- If you're sending data too fast, the Serial Monitor can’t keep up, which might be causing the garbled output. Adding a
delay()can help prevent that.
