In order to check if your board is connected to the Arduino IDE, you can go to Tools -> Port. It should show all the available COM ports.Now, you can disconnect your board. If one COM port disappears, then you can be sure that your board was connected and detected by the Arduino IDE.This practice also helps you identify the correct COM port corresponding to your board, when multiple COM ports are available. In case your board is not getting detected, there maybe some issues with the USB Drivers. On Windows, you can open Device Manager, and open Ports (COM ... Read More

Sometimes, you are just curious to know where the source files of Arduino are hidden. In other words, from where does Arduino know what to do when you write Serial.print(). Or where are the source codes of various libraries like SPI or Wire are stored.The Arduino Source Code files can be accessed by going to the directory containing your Arduino Software. On Windows, you can type Arduino in the start, right-click on Arduino and click on 'Open File Location'. If this opens a shortcut icon, you can right-click on the shortcut icon and again click on 'Open File Location'.This will ... Read More

Updated on 23-Mar-2021 11:10:46
The Serial Plotter is available in Arduino Versions 1.6.6 and above. It is a handy tool for visualizing rapid incoming data, say from a sensor. With Serial Monitor, you may not be able to register the changes in the data, especially if the data is changing too quickly. Serial Plotter will visually show you the changes. What's more, the Serial Plotter can also plot multiple values at a time. I think an example will best explain this.Have a look at the code below. We are generating random numbers, but these could very well be readings from Analog or digital sensors.Examplevoid ... Read More

In order to view Serial output (basically see whatever is printed by the device using Serial.print() or its variants), you can use the Serial Monitor built into the Arduino IDE.First connect the board to the Arduino IDE. This should show a new COM port in Tools -> PortIn case you see multiple Serial Ports, it will be a good idea to disconnect your board and see which port disappears. That way, you can identify the port corresponding to your board. Once you have selected the correct Port, click on Tools -> Serial Monitor or press Ctrl + Shift + M ... Read More
