The official Arduino blog has today published an article which shows how Arduino hardware and a companion Android application have been used by the winner of the South African National Barista Championship, Neil Maree, to roast coffee to perfection.
Maree, a passionate coffee enthusiast, created a company called Genio to build state-of-the-art roasting machines. Over the years, he has perfected these devices, thanks to an innovative Android application that allows users to tweak the settings and achieve the perfect roast every time.
The Role of Arduino in Coffee Roasting
The Android application sends the data to a modified Arduino Due that controls the roasting process. The Arduino Due is a powerful microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller, making it ideal for handling the complex tasks involved in coffee roasting.
All of Genio’s roasters are equipped with a control panel featuring a variety of traditional switches and knobs, as well as a not-so-traditional tablet mount. This setup allows for both manual and automated control of the roasting process. The app sends a “roast profile” to the roaster over a Bluetooth connection, ensuring that each batch of coffee beans is roasted to the exact specifications desired.
How the Android Application Enhances the Roasting Process
The Android application is a game-changer in the world of coffee roasting. It allows users to create and save multiple roast profiles, which can be easily accessed and modified. These profiles include various parameters such as temperature, roasting time, and airflow, which are crucial for achieving different flavors and aromas in the coffee.
For example, a light roast might require a lower temperature and shorter roasting time to preserve the beans’ natural acidity and fruity notes. On the other hand, a dark roast would need higher temperatures and longer roasting times to develop a rich, bold flavor. The app makes it easy to switch between these profiles, ensuring consistency and precision in every batch.
Moreover, the app provides real-time data and feedback during the roasting process. Users can monitor the temperature, time, and other variables on their tablet, making adjustments as needed. This level of control is particularly beneficial for professional baristas and coffee roasters who need to maintain high standards of quality.
Benefits of Using Arduino and Android in Coffee Roasting
The integration of Arduino and Android technology in coffee roasting offers several benefits. Firstly, it enhances precision and consistency, which are critical for producing high-quality coffee. The ability to control and monitor the roasting process in real-time ensures that each batch meets the desired specifications.
Secondly, the use of an Android application makes the system user-friendly and accessible. Even those who are not tech-savvy can easily navigate the app and create custom roast profiles. This democratizes the art of coffee roasting, allowing more people to experiment and discover their perfect roast.
Lastly, the combination of Arduino and Android technology makes the roasting machines more versatile. They can be easily updated with new features and improvements, ensuring that they remain at the cutting edge of coffee roasting technology.
