Serial.print Serial Port Problem

Never used to have this problem. Now my Serial.println("Hello World"); prints garble.

My code: void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600);


// the loop routine runs over and over again forever: void loop() {

Serial.println("Hello World"); delay(1000); // delay in between reads for stability }

Serial Monitor Output: 0⸮~?⸮4⸮!⸮⸮⸮⸮OCAG⸮⸮

Any help would be appreciated. I have selected the right COM port, Matched the baud rate, reinstalled Arduino IDE and tried Atom with Platform IO.

Thanks in advance.

Can you try to use another USB port, and/or another USB cable?

Works fine in CREATE and the desktop IDE serial monitors.

Suspect you may have another issue. Maybe with your OS which you forgot to mention.

Might be worth your READING THIS post then add any missing information.


Did you set the baudrate correctly in the Serial Monitor?
