Arduino (any compatible board), HC-SR04 Ultrasonic Sensor, Jumper Wires, Breadboard (optional), #Circuit Diagram: Trig Pin of HC-SR04 → Arduino Pin 9, Echo Pin of HC-SR04 → Arduino Pin 10, VCC of ...

The provided Arduino code performs the following actions: Initializes pins and serial communication. Measures the distance using the ultrasonic sensor and calculates the distance in centimeters.

I will use this sensor (or its latest version) in a more complex project in the next part of this post. Stay tuned for that do it yourself project. Below is the Arduino Sketch used to test the ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

This study focuses on the development of an obstacle avoidance robot controlled by an ultrasonic sensor. The robot utilizes robotics and artificial intelligence techniques to improve obstacle ...

The treat in question is detected by an SR-04 ultrasonic distance sensor connected to an Arduino Nano. All in all this was a highly successful build as far as neighborhood entertainment value goes.
