Where do serial print characters go?

If I use a Serial.print or serial.println command, where can I see the characters? My understanding is the characters are printed to the Serial Monitor, but where can I see its contents? In other words, if I make a sketch in which the Arduino is told to Serial.println(65) that should send ASCII character 65 (which should be "a") to the serial monitor. But I want to see that character somewhere on the computer. I am running a Mac. Where can I see the character? I do not have the Arduino connected to an LCD or TFT screen.


You have a serial monitor in the Arduino IDE.

Maybe with the pictures attached is more clear.

Excellent. Thank you so much.

Hi, See "How To Use the Arduino Serial Monitor" on the ArduinoInfo.Info WIKI HERE:
