Project description In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to ...

The ultrasonic sensor measures the distance from the sensor to the water surface, which is then used to calculate the water level as a percentage. Based on this value, the Arduino decides whether to ...

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 ...

As shown in the block diagram, the Arduino microcontroller constantly monitors the values from the ultrasonic sensor which is placed outside the dustbin. When a person comes near the dustbin the ...

Project Hardware Software Selection Arduino Uno - It is a microcontroller that gives commands to the robot. Motor driver - It helps to control the motor attached to the robot, it is connected with ...

In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle.

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.
