THIS CODE WILL PROVIDE A DEMO USE OF THE HC-SR04 CONNECTED TO AN ARDUINO NANO (ATmega328p) THINGS YOU NEED FOR THIS DEMO: 1.) Install Arduino IDE 2.) Install CH340 Driver (Google how to install CH340 ...

Simple arduino code to poll and oversample the inexpensive HC-SR04 Ultrasonic Rangefinder board without libraries The current code is written for the NodeMCU V2 board (an ESP8266 breakout board) but ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...

ABSTRACT: In this study, a simple Arduino-based experiment was designed to examine the acceleration of the object during free fall and to calculate the value of “g” (acceleration due to gravity).
