… usar, los alumnos simplemente tienen que conectar el dispositivo Android a la placa, montar el proyecto, y después usa los sensores que contiene la shield y los módulos plug-and-play para simular las atracciones. Los datos son transmitidos del experimento a el dispositivo móvil del alumno via Bluetooth, donde se puede ver y analizar el resultado obtenido en la app Science Journal de Google o en las fichas de los alumnos. Arduino Education Science Kit Physics Lab no está pensado para usarse únicamente en clase. De hecho, los alumnos pueden usar el kit en exteriores para convertir su recreo en su propia feria de ciencia aplicando los conceptos que han aprendido, y así, diseñar y probar sus propias atracciones. Basado en el uso de Arduino MKR WiFi 1010 , que es un laboratorio portátil incluyendo un grupo de sensores para medir luminosidad, temperatura, movimiento, campos magnéticos y mucho más… todo esto en una caja Gratnells protectora. Arduino Education apunta a apoyar a los profesores proporcionando nuestros programas, contenido online y las hojas del alumno en el mayor número de idiomas posible: no solo en los idiomas Europeos relevantes, por ejemplo, Árabe y Japonés están planeados para futuras actualizaciones. Lo siguientes idiomas para Science Kit Physics Lab serán Alemán, Húngaro y Portugués. MÁS INFORMACIÓN Da oggi Science Kit è disponibile anche in italiano e spagnolo. Nel Gennaio 2019, in collaborazione con Google, Arduino Science Kit Physics Lab è stato lanciato sul mercato, per studenti di scuola media (tra 11 e 14 anni) e non solo, con l'obiettivo di esplorare la scienza, divertendosi. Da oggi, i contenuti del corso sono disponibili in italiano e spagnolo, rendendolo ancora più accessibile. “Sei tu che esperimenti in prima persona, ed è stato davvero divertente poterlo fare” ha commentato uno studente inglese dell'accademia di ARK Burlington Danes.

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.
