Ultrasonic range finder using 8051 mictrocontroller has been already published by me in this website. This time it is an ultrasonic range finder using arduino. HC-SR04 ultrasonic range finder module is used as the sensor here. The display consists of a three digit multiplexed seven segment disp...
The complete board is powered by a 9V battery. The brain of the circuit is Arduino Nano. Three Ultrasonic sensors are used for obstacle detection in the left, right, and front of the stick. Two of the four pins of these three sensors, namely VCC & GND, are connected t...
The circuit consists of an ultrasonic sensor to measure the distance and an LCD Design. Introduction. How far are you?, what is the distance?The answers. Pipe length Measurement Circuit. 3d ultrasonic PositioningCircuit. Ultrasonic Rat Repellent Circuit. Sonic Distance measurement (not ultrasonic)....
An interesting solution to a problem comes from the transducers having a polarity, but because it doesn’t matter in their usual application, that polarity not being marked. He’s overcome this by using the STM32 he has managing power alongside his BeagleBone to listen through a sensor as the...
