In order to program a board using Arduino IDE, first make sure that the correct board is selected in Tools -> Board, and also make sure that the board is connected to your machine and the correct COM Port is selected.Once you've done the basic verifications, you can click on the Upload button on the top left.Alternatively, you can click on Sketch -> Upload.Make sure that you don't select the Upload using Programmer option if you are trying to upload the sketch using the USB. Upload Using Programmer option has to be used when you use an external programmer to ... Read More

There are two ways to compile code using the Arduino IDE.You can click the tick-mark button at the top-left. That will begin the compilation.Alternatively, you can go to Sketch -> Verify/ CompileThe compilation progress will be shown at the bottom of the screen.If you'd like to see Verbose print statements at the bottom when the compilation is in progress, you can go to File -> Preferences and click on the Show Verbose Output during Compilation checkbox −Below that, you can also define the kind of compiler warnings you wish to receive. Click OK after you are done with the settings. ... Read More

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 may feel the need to define your own custom header files, for organizing your code better. Say you want to create a global_variables.h file for storing all your global variables.You can create the file within Arduino IDE by clicking on the bottom arrow at the top right of the screen, and selecting 'New Tab'. (Alternatively, you can press Ctrl+Shift+N on your keyboard)Name your file in the prompt and press OK.The new file gets created, and can be found in your Sketch folder.In order to include this file in your main .ino code, you can simply add the following ...

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

To see inbuilt examples in Arduino IDE, follow the steps given below −Step 1: Go to File.Step 2: Click Examples from the dropdown menu.Step 3: Select the relevant example from the category of your interest.If you add separate boards like ESP32 to your Arduino IDE, you can also see examples specific to that board, if you've selected that board from Tools -> Board

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

In order to download a new library, go to Tools -> Manage LibrariesSearch for the library of your interest in the window that opens up. Click on the desired library, and click Install.This will Install the library and you will be able to see the example specific to the library from File -> Examples.

To add a new board in Arduino IDE, go to Tools -> Board -> Boards ManagerIn the window that opens up, search for the board of your interest, click on that board, and click on the 'Install' button. You can even choose to install an earlier version of the board from the versions dropdown (1.1.6 in the image below).Some boards are not directly searchable in the Arduino Boards Manager. Popular examples are ESP32 and ESP8266. In order to install the ESP32 and ESP8266 board in Arduino, the following steps can work (other non-available boards may have similar steps).Step 1: Get ...
