In this project, we will create a WiFi-controlled scheduled relay using a NodeMCU v3, which can be turned on and off at specific times set via a web interface. The current GMT will be displayed live on the server. This project is perfect for automating devices such as lights or Read more
This is a small article with a basic feature of LM555 or NE555 timer IC. This timer IC is very common and can be used in different circuits in different operating configurations. In this article, we are going to generate a PWM signal using NE555 timer IC. What is PWM Read more
When you are working with electronics, especially power electronics you must have to measure line frequency. But in most cases, people do not have a frequency meter. If you knew how to make a frequency meter in a very easy way, you would make one for yourself. Here in this Read more
Sometimes, we need to add LCD with the project while the micro-controller itself has limited free pins for LCD. In that case, we can use shift registers to interface LCD with a micro-controller. After reading this article, you’ll be able to do that yourself. It’s easy! So let’s start Interfacing Read more
