Abstract: Abstract A wearable microcontroller-free motion and obstacle detection system is disclosed in the form of smart glasses to assist visually impaired individuals during real-time navigation. The system comprises an HC-SR04 ultrasonic sensor mounted on a lightweight eyeglass frame to continuously scan the ambient environment using high-frequency acoustic waves. Upon identifying an obstacle within a predefined threshold zone, the sensor generates an analog trigger signal directed to an IC 555 timer configured in monostable mode. The IC 555 timer produces a high-voltage output pulse for a mathematically deterministic duration governed strictly by an external resistor-capacitor (RC) network. This output pulse biases a BC547 NPN transistor switch into saturation, thereby closing a direct-current circuit to activate an alert unit, such as a buzzer or vibration motor. The architecture completely eliminates software dependencies, programming requirements, and processing latencies, yielding a low-cost, compact, and highly energy-efficient navigational aid.
