1.	If 1 means an object is detected and 0 meaning no object is detected, then considering the sensor is stationary, what can be said about the movement of the object if the output by the sensor is 1010101?(a) Object is stationary(b) Object is oscillating side by side(c) Object is continuously moving away(d) Object is continuously moving closerThis question was posed to me in class test.I need to ask this question from Ultrasonic Sensor in portion Interfacing of Sensors, Actuators, and Other Modules of Arduino
Answer» The correct answer is (b) Object is oscillating side by side To elaborate: The only explanation for such output from the SENSOR would be if the object is moving in such a PATH, that makes it WITHIN the range of the sensor and VICE versa after each specified amount of time and this continuously happens along a deterministic path so that we know that the only way this can happen is that if the object is oscillating between two given POINTS.
