## Description

DIY kit for electronics enthusiasts, which displays texts and LED patterns during rotation thanks to the microcontroller and 12 SMD LEDs. It is assembled by SMD hot air soldering, providing a practical learning experience. It works with 2 CR2032 batteries not included, and the effects can be customized via downloader and external programmer, for educational and creative projects.
DIY Kit Spinner with Two Paddles for the Finger (Fidget Spinner), SMD, ideal for electronics enthusiasts and educational projects. With the help of a microcontroller and 12 strategically placed LEDs, the gyroscope displays text or visual patterns during rotation on the finger. It is powered by two CR2032 type batteries ( NOT included) , representing an opportunity to learn about electronic circuits and microcontrollers by assembling it. With the customization function available through the downloader (requires a separate programmer, for example, PL2303), the visual effects can be modified according to preferences, making each gyroscope a unique project.
Customizing animations requires solid programming knowledge.
The kit includes a microcontroller board and SMD electronic components that require soldering with a hot air gun, giving users the opportunity to experience manual circuit assembly. Batteries are not included.
