Building a human-following robot using Arduino and three ultrasonic sensors is an interesting project. What makes this project particularly interesting is the use of not just one, but three ultrasonic ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

In this project I measure the distance using Ultrasonic sensor. By looking at my code you can see If Else for each range of distances and some actions take place in each one. LEDs are used for ...

These ultrasonic sensors will send an Ultrasonic wave using the ultrasonic transmitter of the sensor. These ultrasonic waves travel through air and on colliding with an obstacle, get reflected back.

IoT Based Smart Bin. IoT-Based Smart Bin project features a custom-built IoT system and Firebase database, using the Arduino Uno R4 WiFi. Dual ultrasonic sensors handle motion and fill-level ...

We burn a C Code on Arduino Nano to tell the microcontroller board how and what operations to perform. Arduino Nano has exactly the same functionality as Arduino Uno but in quite a small size. The ...

How the Arduino ultrasonic sensor actually works. To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate ...

This servo motor has no role in operation and also added unnecessary complications. So I removed this servo and IR sensors and use 3 ultrasonic sensors. With ultrasonic sensors, you can measure ...
