Arduino Tutorials & Arduino Projects | Serial Monitor and Serial Communication

The Serial Monitor is a frequently utilized visualization method in Arduino tutorials and Arduino projects, serving as a common means of monitoring.

The Serial Monitor is a tool used in Arduino programming for monitoring and debugging the communication between an Arduino board and a computer. It allows users to send data from the Arduino to the computer and vice versa, providing a way to observe the behavior of the program and the values of variables in real-time.

By displaying information sent from the Arduino via the Serial library, the Serial Monitor enables developers to:
Debug Code: Developers can print out variable values, sensor readings, or other debug messages to the Serial Monitor to understand how their code is functioning and identify any issues or errors.
Monitor Sensor Readings: When working with sensors connected to the Arduino, developers can use the Serial Monitor to view the sensor readings and ensure they are functioning correctly.
Interact with the Arduino: Users can send commands or data from the Serial Monitor to the Arduino, allowing for interactive control of the Arduino board.

Overall, the Serial Monitor is a crucial tool in Arduino development, providing insights into program execution and facilitating communication between the Arduino board and external devices.

To open the Serial Monitor, we need to select Serial Monitor from the Tools menu of the Arduino IDE software. The Serial Monitor can also be opened using the shortcut key combination CTRL+Shift+M.

In the Arduino Uno model, there is one port for serial communication. Digital pins 0 and 1, namely TX and RX pins, are used for serial communication. Additionally, serial communication can be done via USB. The Arduino Mega and Due models have 4 serial port features.

Arduino uses the following codes for serial communication:
available() availableForWrite() begin() end() find() findUntil() flush() if (Serial) parseFloat() parseInt() peek() print() println() read() readBytes() readBytesUntil() readString() readStringUntil() serialEvent() setTimeOut() write()

For now, we will use the begin(), print(), and println() commands for serial communication. The usage of these commands is as follows:
