We’re excited to announce the launch of the new Arduino IoT Bundle. This is built to help you dive into the complex and fascinating world of the Internet of Things with even more confidence and possibility — giving you the hardware, software, and components you need to create your own connected IoT projects. So how does it all work? Let’s find out more. What is the Arduino IoT Bundle? Getting started with the IoT can be a daunting process. It requires a certain set of tools and a level of knowledge to take those first steps, but building your own connected IoT devices can be an incredibly rewarding process once you figure out the basics. The Arduino IoT Bundle is designed to bring together all the tools and knowledge you’ll need to get started with your first connected IoT devices. It’s built around the Arduino Nano RP2040 Connect, and the bundle also contains electronic components and a series of step-by-step tutorials to help you get started quickly and confidently. How it works — some examples The IoT is an incredibly rich area when it comes to building your own connected projects. There are a ton of exciting opportunities here that don’t require an enormous amount of knowledge or resources to get started with. Let’s take a look at some examples of IoT projects, you’ll find more in the bundle: Pavlov’s Cat Training a cat is a tricky business, as any feline owner will know all too well. However, you can now use technology to make this task easier, using an IoT-enabled device you build at home to keep your cats in line. This project — using only components found in the Arduino IoT Bundle and some cardboard — allows you to build a device that plays a certain melody whenever it dispenses food for your cat. At other times, it will play a different tune and your furry friend gets nothing. Just like Pavlov and his famous dogs, you’ll be able to train your cat to associate certain sounds with a reward
FAQs
Is the Nano ESP32 compatible with MicroPython?
Absolutely! This board fully supports MicroPython. For detailed information on setting it up and getting started with MicroPython, please visit docs.arduino.cc/nano-esp32.
How can I power the Nano ESP32?
The Nano ESP32 can be powered in two ways. Firstly, you can power it via the USB port, which activates the VBUS pin as an output. Alternatively, you can supply power through the VIN pin, accepting an input voltage range of 5 to 18 Volts.
Does it use the official ESP32 core?
