Utilizing the latest technology, these buzzers feature a WeMos D1 microcontroller, which is powered by a 2000mAh battery via a battery shield. The system is controlled by a Raspberry Pi, which receives input from the buzzers, processes the information and outputs sound through two attached speakers using a HiFiBerry AMP2 header board.

The WeMos D1 microcontroller is programmed using C language, which allows for efficient and precise control of the buzzers. The Raspberry Pi, on the other hand, uses Python for its code, making it easy to process the buzzer inputs and output sounds. The buzzers are connected via WiFi, which allows for easy and seamless communication between the devices.

The body of the buzzers has been completely redesigned to fit the microcontroller, battery, and USB-C jack for charging, which makes it compact and easy to use. This new body was printed using an FDM printer, which provides high-quality and precise design.
