“The current measurement requires the use of an ammeter placed in series with the load. An ideal ammeter has no voltage drop, i.e. it is a short circuit. But most of the current sensors are based precisely on the …

“I’ve been reading Sapiens by Yuval Harari and one of the things that has been the most fascinating to me, is human beings ability to make their life better by envisioning and creating a tool that doesn’t yet …

“Hello there, hope you are doing good and in this tutorial I will be showing you how i made a current sensor for Arduino using some very basic electronic components and a home-made shunt. This shunt can easily handle large …

“In the 1980s, there was no internet as like today and so the sources of entertainment were televisions, radios and cassette players. When I was a kid, we had an audio cassette player. We used it to play songs but …

“The 555 Timer IC is one of those evergreen and versatile ICs that finds place in every common place electronics applications. What does it do? It generates a square wave used in timing applications and many other fields. It mainly …

“IR is a complex piece of technology yet very simple to work with. Unlike LEDs or LASERs, Infrared cannot be seen with the human eye. In this Instructable, I will demonstrate the use of Infrared through 3 different circuits. The …

“This Arduino based digital clock is synchronized by the 60Hz power line. It has a simple and inexpensive common anode 4 digit 7 segment display which shows hours and minutes. It uses a cross over detector to detect when the …

“First of all, thanks for landing this post, if you are searching for Heartbeat Sensor | Heart Rate Sensor | IR Pulse Sensor then we must say you are in the right place. So, without getting into query let’s directly jump …

“This project is my attempt to build LED color organ and VU meter both combined. The color of the LED depends on the frequency of the audio signal. The number of rows(i.e, arcs) depends on the amplitude of …
