Check the below project to measure the distance of any object and to properly understand the Ultrasonic sensor working: Working this Arduino Door Alarm is very easy. Whenever anyone comes in the ...

if the door is then sensed to close after it was already open the buzzer will turn off. Keep in mind that the ultrasonic sensor requires the signals trig and echo to be a PWM. If the pins are changed ...

Persnonal Project where I programmed and wired an embedded system using an Arduino ATMega328 microcontroller ... If an object or person crosses the sensor and reflects the ultrasonic waves, it ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module ... cm from the HC-SR04 module), and an ear-splitting beep from the piezo-buzzer otherwise.

Using an Arduino Nano, ultrasonic sensor, and buzzer, it can sense objects in their way and provide an instant audible alert to them. So they can navigate independently. The best part of this blind ...

The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

The technology can indeed neutralize human disability; with this in mind let us use the power of Arduino and simple sensors to build a Blind man’s stick that could be a lifesaver for visually impaired ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

As we know that not all cars come with parking sensors. If we want to install an external parking sensor, it costs a lot of money. But luckily we can make a low-cost parking sensor by using Arduino.
