<![CDATA[The development of microcontroller technology opens up significant opportunities for the development of mobility aids for people with disabilities, particularly the visually impaired. This research designed and developed an Arduino-based Blind Stick that helps users detect obstacles around them. The system utilizes an ultrasonic sensor for distance detection, a buzzer for audio alerts, and a vibration module to provide tactile feedback when an object is within a certain distance. Data received by the sensor is processed by an Arduino microcontroller, enabling a fast and accurate response. Test results indicate that the device is capable of detecting objects within an effective range according to the user's mobility needs and providing easy-to-understand alerts. Therefore, this Arduino-based Blind Stick is expected to improve the safety, independence, and quality of life of visually impaired users in their daily activities]]>
