This example code is in the public domain. // to calculate the note duration, take one second divided by the note type. //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.

This project implements an encoder-based measurement system and PID control for motor speed using Arduino. It includes pulse reading, speed calculation, and closed-loop PID control with simulation ...

Abstract: This paper presents the simulation and experiments performed on a microelectromechanical system (MEMS) electrostatic field sensor with a virtual ground. Virtual ground is usually used when ...

Abstract: This paper presents the characterization of a heterocore fiber optic refractive index (RI) sensor for discrete interrogation as a function of wavelength. The structure consists of a ...

Motion detectors are useful smart home devices for creating simple automations, such as turning on your lights when you enter a room or being alerted to motion in your home when you're away. Standard ...
