A riddle wrapped in an enigma... made easy, with Arduino Plug and Make Kit
A riddle wrapped in an enigma... made easy, with Arduino Plug and Make Kit
November 15, 2024

The Arduino Plug and Make Kit was designed to open up infinite possibilities, breaking down the idea that technology is a “black box” reserved for experts. With its snap-together system, this kit gives everyone – beginners and seasoned makers alike – the power to create and innovate without barriers. Forget being a passive user! With the Plug and Make Kit, technology is accessible and ready to bring your ideas to life. Meet Giulio Pilotto, Plug and Make Kit Star Giulio Pilotto is one of Arduino’s senior software engineers and works closely on Arduino Cloud projects. When we held a “Make Tank” workshop at our Turin office to showcase the potential of the Plug and Make Kit, he joined in with inspiration from a recent escape room experience. The result was Riddle Treasure, a puzzle-based game that allows you to recreate the excitement of an escape room anywhere you are. At this year’s Maker Faire, Pilotto had the opportunity to present Riddle Treasure at the Arduino booth. While he had showcased his own creations at previous Maker Faire editions, this time felt special: “The Maker Faire is always a wonderful high-energy event,” he says. “I was happy to represent the Arduino team as we focus more than ever on the community: all our products were presented in the light of what people can do with them.” Riddle Treasure To be honest, this is probably the most advanced project our in-house “Make Tank” came up with (so far!). After all, it has to be somewhat complicated to emulate intricate escape room puzzles! However, following Pilotto’s step-by-step instructions on Project Hub and leveraging the easy snap-together mechanism of Modulino nodes, anyone can recreate Riddle Treasure – or even invent a personal, unique variation. The goal of the game is to unlock a safe. But to get there, you need to complete three steps in order. 1. Combination Lock: First, you must rotate the encoder in Modulino Knob like a

FAQs

Can I use hardware compatible with the Arduino UNO R3 with the Arduino UNO R4 Minima?

Yes, the Arduino UNO R4 Minima was specifically designed to ensure compatibility with previous shields and compatible hardware developed for the Arduino UNO R3. The UNO R4 Minima maintains the same mechanical and electrical compatibility, allowing you to seamlessly use your existing shields and hardware with the new board. This makes it easy to upgrade to the UNO R4 Minima without the need for significant changes or adaptations to your projects.

Can I use my sketch developed for the UNO R3 in the UNO R4 Minima?

Yes, if your sketch was developed using the Arduino API. In case you are using instructions only available for the AVR architecture, some changes need to be made to ensure compatibility.

Are all libraries compatible with the UNO R3 also compatible with the UNO R4 Minima?

No, some UNO R3 libraries use instructions of the AVR architecture that are not compatible with the architecture of the UNO R4 Minima, however there are libraries that have already been ported as part of our early adopters program or are based on the Arduino API
