We know that LED is a two terminal semiconductor device. It is used in most of the electronic circuits as a sign or visual representation to the normal human to know that circuit is working properly.

What is an ESP32 Web Server? In the Internet, all the websites are hosted on a computer and this computer is called a server. Since this particular server is used to serve web pages and web requests, ...

In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights. The building process is simple and requires only a few transistors, capacitors ...

Abstract: This paper depicts the implementation of a colorful RGB-LED light source with an 8-bit microcontroller. The microcontroller regulates LED light output with pulse-width modulation current and ...

Proteus is a software for microprocessor simulation, schematic capture, and printed circuit board (PCB) design. The Proteus Professional demonstration is intended for prospective customers who wish to ...

In this project we are introducing a simple circuit and code that will allow you to create fully programmable and customizable earrings. We are also leveraging the mighty power of the ATtiny85 ...

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for a ...

LEDs are a staple component in most circuits. Using Ohm’s law, we can easily calculate the conditions for the theoretical lighting intensity we’re after. LEDs are a staple component in most circuits.
