RESEARCH: SENSORS ULTRASONIC RANGE FINDER An ultrasonic range finder sensor enables a robot to detect obstacles in its path by utilizing the propagation of high-frequency sound waves. The sensor emits a 40 kHz sound wave‚ which bounces off a reflective surface and returns to the sensor. Then‚ using the amount of time it takes for the wave to return to the sensor‚ the distance to the object can be computed. Unlike the bumper switch and limit switch that alert you when they have been hit‚ the ultrasonic

system. This is a simple but effective internal intercom system for homes‚ offices‚ schools‚ colleges or banks. The system is designed for up to seven sets‚ each of which generates a pulse code when dialing a number or type in. This project uses a microcontroller to provide different functions. The circuit provides a simple illustration of a telephone intercom system that has bidirectional communication with the characteristics of LM386 amplifier. Our system consists of a central control unit which can
