A Loud-ball ("L-Ball") is a prototype ball designed using an electronic circuit that produces non-stop sound intensity during play. This study focuses on prototype design by considering the selection of mechanically strong lightweight electronic components, such as batteries and buzzers.   Sport is an inherent, low-cost way of encouraging dynamic and spatial training for disabled persons. It increases community social boundaries and diversity with higher participation. Compared to their peers with normal vision, visually impaired children urgently need sports activities. This is because visual impairment limits their involvement in play, which noticeably delays their physical development. Several electronic vision aids have been developed. However, most are designed to improve mobility skills for the visually impaired, including robotic devices, such as sensor blind stick, and distance measuring glasses.   Loud Ball (L-Ball): Loud ball is an electronic audio ball that sounds continuously, making its position easily detected by the visually impaired. This sport is played by adapting to the goalball game. The main controlling part is Arduino with which the MEMS ADXL345 is interfaced. MEMS sensor does the sensing part. This sensing is done in two ways. One way is to sense when the ball is just held in player’s hands. The second case is when the ball is in motion or if it is kicked. In the first case, the Buzzer gives sound in one pattern and in other case, it gives faster sound than the first case. That’s how the blind players can know the position of the ball and get through the game.

 

The major features of this project are:

• Using Arduino to achieve this task.
• Using MEMS ADXL 345
• Using Piezobuzzer to give different kinds of sound pattern
