What is Arduino IDE 2.0?
Arduino IDE 2.0 is an open-source project that aims to provide a faster and more powerful programming tool for Arduino users. It is based on Theia, a modern web-based framework for developing cloud and desktop applications. Arduino IDE 2.0 has a revamped user interface, improved board and library manager, autocomplete feature, code navigation, live debugger, and much more.
Features and benefits of Arduino IDE 2.0
Some of the main features and benefits of Arduino IDE 2.0 are:
Flexible user interface: You can customize the layout of the editor, change the theme, adjust the font size, zoom in and out, split tabs, and more.
Autocomplete: The editor can suggest the completion of variables and functions according to your code and the libraries you included. This can help you write code faster and avoid errors.
Code navigation: You can right-click on a variable or a function and jump to its definition or declaration in your code. You can also use the outline view to see the structure of your sketch.
Live debugger: You can set breakpoints, inspect variables, watch expressions, step through your code, and more with the built-in debugger tool. You can use it with supported boards such as Arduino Zero, Nano 33 IoT, MKR1000, etc.
Local and cloud projects: You can save your sketches locally on your computer or sync them with Arduino Cloud, where you can access them from any device using the Arduino Web Editor.
Better search: You can search for keywords in your code using the search bar or use the advanced search tool to find and replace text in multiple files.

After you have installed Arduino IDE 2.0, you can start using it to create and upload sketches for your Arduino boards. Here are some of the basic steps you need to follow:
Creating and editing sketches
To create a new sketch, you can go to File > New or press Ctrl+N. You will see a blank editor window where you can write your code. You can also open an existing sketch from File > Open or press Ctrl+O. You can browse the examples from File > Examples or press Ctrl+Shift+O. You can save your sketch from File > Save or press Ctrl+S.
To edit your sketch, you can use the toolbar buttons or the keyboard shortcuts to perform actions such as cut, copy, paste, undo, redo, comment, indent, etc. You can also use the autocomplete feature by pressing Ctrl+Space to get suggestions for completing your code. You can use the code navigation feature by right-clicking on a variable or a function and choosing Go to Definition or Go to Declaration. You can also use the outline view to see the structure of your sketch.
Using the autocomplete feature
The autocomplete feature is one of the most useful features of Arduino IDE 2.0. It can help you write code faster and avoid errors by suggesting the completion of variables and functions according to your code and the libraries you included. To use it, you need to press Ctrl+Space while typing your code. A pop-up window will appear with a list of possible completions. You can use the arrow keys to navigate through the list and press Enter to select the one you want. You can also type more characters to narrow down the list.
Using the debugger tool
The debugger tool is another powerful feature of Arduino IDE 2.0. It can help you find and fix errors in your code by allowing you to set breakpoints, inspect variables, watch expressions, step through your code, and more. To use it, you need to have a supported board such as Arduino Zero, Nano 33 IoT, MKR1000, etc. You also need to enable debugging from Tools > Debugging or press F5.
To set a breakpoint, you need to click on the left margin of the editor window next to the line of code where you want to pause the execution. A red dot will appear indicating the breakpoint. To remove a breakpoint, you need to click on it again.
To start debugging, you need to click on the Debug button on the toolbar or press F5. The program will compile and upload to your board and then pause at the first breakpoint or at the beginning of the setup() function if no breakpoints are set.
To inspect variables, you need to hover over them with your mouse cursor or look at the Variables panel on the right side of the window. You can also add variables to the Watch panel by right-clicking on them and choosing Add Watch.
To step through your code, you need to use the buttons on the toolbar or the keyboard shortcuts to perform actions such as Step Over (F10), Step Into (F11), Step Out (Shift+F11), Continue (F5), Stop (Shift+F5), etc.
Using the serial monitor and plotter
The serial monitor and plotter are tools that allow you to communicate with your board and visualize data sent from it. To use them, you need to have your board connected to your computer via USB and select the correct port from Tools > Port.
To open the serial monitor, you need to click on the Serial Monitor button on the toolbar or press Ctrl+Shift+M. A new window will appear where you can see the data sent from your board and send data back to it using the input box at the bottom. You can also adjust the baud rate and other settings from the drop-down menus at the bottom.
To open the serial plotter, you need to click on the Serial Plotter button on the toolbar or press Ctrl+Shift+L. A new window will appear where you can see a graph of the data sent from your board. You can also adjust the baud rate and other settings from the drop-down menus at the bottom.
Syncing sketches with Arduino Cloud
Arduino Cloud is a service that allows you to store and access your sketches online using the Arduino Web Editor. To use it, you need to have an Arduino account and sign in from the Arduino IDE 2.0. You can do this by clicking on the Arduino icon on the top right corner of the window and choosing Sign In.
Once you are signed in, you can sync your sketches with Arduino Cloud by clicking on the Sync button on the toolbar or pressing Ctrl+U. You can also access your cloud sketches from File > Open Cloud Sketch or press Ctrl+Shift+U. You can browse your sketches by name, date, or board type.
By syncing your sketches with Arduino Cloud, you can benefit from features such as:
Backup and restore: You can keep your sketches safe and recover them in case of data loss.
Sharing and collaboration: You can share your sketches with other users and collaborate on projects.
Remote access: You can access your sketches from any device using the Arduino Web Editor.
Cloud integration: You can connect your sketches to other cloud services such as IoT, AI, etc.
