Blind Aid is a project that utilizes ultrasonic waves to assist blind individuals in detecting obstacles and navigating safely. By employing ceramic transducers operating at 40kHz, the system can detect movements within a range of 25 cm to 6 meters. When an obstacle is detected, an alarm sound is triggered, providing immediate feedback to the user. This innovative solution enhances the mobility and independence of blind individuals, allowing them to navigate unfamiliar environments with greater confidence and safety
