DigiKey - Arduino Plug and Make Suitcase Synthesizer – Potentially Genius | DigiKey
Tomorrow Lab, an invention studio, partners with Arduino to explore the potential of the Arduino plug-and-make kit, a beginner-friendly DIY electronics kit. The kit allows users to easily connect modular components to create interactive projects. Alessandro Raluchi from Arduino introduces the kit, emphasizing its accessibility and fun. Tomorrow Lab is challenged to create a unique application, leading to the development of a suitcase synthesizer. This synthesizer integrates various modules, including capacitive touch keys, a buzzer, and sensors, to create a portable musical instrument. The project involves designing a custom PCB, utilizing 3D printing for structural components, and programming for interactive features. The final product is a foldable synthesizer that combines multiple electronic modules in a cohesive and functional design, demonstrating the versatility and creativity possible with the Arduino kit.
