Autozero circuit that allows the user to automatically adjust the zero-point virtual ground terminal of the scope with the ...

The smart water controller for metro water supply lines described in this work makes use of a relay, an ultrasonic sensor, a flow sensor, a solenoid valve, GPS, and GSM. The planned system is intended ...

In order to solve the collision problem of quad-rotor UAV with low flight altitude the method to calculate the distance between the obstacles and UAV by using the ultrasonic sensors is proposed. And ...

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...
