Nowadays, visual indication is a must-have feature for any electronic device, which will make user interaction much easier. There are multiple ways to implement the visual indication, from simple ...

A small tutorial for interfacing a ultrasonic sensor with arduino this uses a sensor called HC-SR04 which sends ultrasonic waves to detect objects in front of it.

In this project we are going to tell you about how to blink an led using 8051 micro controller. We are showing this demo using proteus simulation.

Abstract: This tutorial will provide a holistic overview of modern circuit techniques for interfacing to the human body: both sensing of key biomarkers as well as delivery of stimulation. A brief ...
