Straight forward, no additional hardware, no BS. Debug your Arduino Uno or Nano (almost) out of the box!

Thanks for the video. For anyone else trying to get this working: Maybe I missed it but there seems to be a step missing – you need to add the avr-debgugger library to your project. Maybe you’ve done this before in VSCode and it’s somehow picked it up in the example shown in this video? There is a series of articles on codeproject by the author of the library (search for “Creating and Debugging Arduino Programs in Visual Studio Code – Part 2″) that has some additional info, though beware he is using the Microsoft Arduino extension (not PlatformIO) so his description of how to add the library to your project is not correct for PlatformIO.

IDE 2.0.2 is available, complete with our usual dose of fixed bugs.

Discover all the new features of the Arduino IDE 2, our faster and more powerful programming tool.

Online interactive development environments (IDE) have taken off during the recent years. Traditionally, local IDEs were considered the best tools for programming as they were usually faster than their online counterparts. But the arrival of new web programming frameworks and the standardisation of high-speed internet connections have improved the user experience of interactive editors using browsers.

Arduino’s popular online IDE is a widely used tool for programming not only Arduino boards but also third-party hardware. Improving the user’s experience including or changing features is part of its dynamic nature, always based on the developers’ experience and feedback.

Remove portability issues
Installing an application to your custom operating system should be a straightforward task, but experience says that it is usually painful to struggle with compatibility issues of your system libraries or drivers. Having a centralised online editor helps you get focused on coding and not maintaining your editor.

Zero setup
Configuration can also be a headache for the non-skilled users that find it difficult to fine tune all the knobs of themes, fonts, plugins and settings. An online editor with a predefined set of configurations simplifies the developer’s lives.

Store your projects online
Storing your projects online you have your data safe. Hard disks, USB sticks or SD cards get corrupted eventually so having your projects stored by default on the cloud prevents you from creating periodic backups to keep your data safe.

Arduino Cloud Adds Support for ESP32-S2, -S3, and -C3-Based Boards
Develop for these popular ESP32 variants in the cloud.

Arduino Cloud extends ESP32 support to S2/S3/C3 devices
https://blog.arduino.cc/2022/09/16/arduino-cloud-extends-esp32-support-to-s2-s3-c3-devices/

Arduino Cloud is Arduino’s integrated platform to develop, deploy, and manage IoT devices in an easy way. It supports a broad list of hardware including not only Arduino boards but also ESP32 and ESP8266-based boards. Arduino is committed to making this list of devices grow and as a result of this effort, ESP32-S2, S3, and C3 families of chipsets have been added to the list of supported devices.

Furthermore, you can use the same Arduino IDE to program Arduino and ESP32 boards. And you can even reuse your code and sketches!

Three new ESP32 flavors supported by Arduino Cloud
The three new ESP32 platforms that are now supported by Arduino Cloud are the popular ESP32-S2, S3, and C3.

ESP32-S2 is a highly integrated, low-power, single-core WiFi microcontroller SoC, designed to be secure and cost-effective, with a high performance and a rich set of IO capabilities.

ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n WiFi and Bluetooth 5 (LE) connectivity that provides long-range support.

ESP32-C3 is a cost-effective RISC-V MCU with WiFi and Bluetooth 5 (LE) connectivity for secure IoT applications.
