Digital Bell Ball

Description of the project: In contrast to a conventional bell ball (i.e. a ball containing a bell for signalling), the digital bell ball developed can emit an acoustic signal even when the ball is stationary. The developed ball can also change its colour and sound frequency depending on the speed. This new development can be controlled via a barrier-free app, which is available free of charge for both Android and iOS devices.
