If baud rate doesn’t match the value set in your sketch setup, characters will be unreadable Sets “line ending” that will be sent to Arduino when you or click send Larger area (can be enlarged by dragging the corner) Image Credits: YourDuino What you see on the Serial Monitorįor typing characters, (hit or click “send”) It may look daunting when first seen, but here’s a classification of what the boxes are with its relative usages When you enter the above code, the serial monitor will appear in a new window.

*********( THE END )*********** Step 3: Understanding the Serial Monitor Interface If (ByteReceived = '1') // Single Quote! This is a character. Serial.println('(Decimal)(Hex)(Character)') Serial.println('- Start Serial Monitor SEND_RCVE -') *-( Declare Constants and Pin Numbers )-*/ SEE the comments after '//' on each line below Displays received character as Decimal, Hexadecimal and Character Receives characters from Serial Monitor Since your Arduino and sketch resets whenever you start the Arduino Serial Monitor, you’ll need an example Serial Communication Sketch to copy and paste /* YourDuinoStarter_SerialMonitor_SEND_RCVE Step-by-step tutorial of the Arduino Serial Monitor Step 1: Preparing what is requiredĬonnect your Arduino board with the USB cable for activation of Serial Monitor Step 2: Copy and Paste Sketch into the Serial Monitor In short, the purpose of the Arduino serial monitor is to help users like yourself to debug Arduino software sketches or viewing data sent by a working sketch. But, for this feature to work, it requires The Serial Monitor, a separate pop-up window that receives and sends serial data for communication. We all know about the Arduino IDE the development environment of Arduino, with a feature that helps users debug sketches and control your device from your computer’s keyboard. Before we begin with the tutorial, here’s a quick introduction to the Arduino Serial Monitor for those that are unsure!
