  If you’re still using traditional keyed locks, then you must be always worrying about losing the key or somebody breaking into your house. With traditional locks, there is higher risk of keys being misplaced or getting into the wrong...
Technology is advancing daily and everything is turning smarter. A number of traditional devices that we used at our homes are becoming smarter now, including the doorbells which are also evolving with new features and styles. Today you will...
Today, home automation using Internet of things (IoT) is one of the major domains which is attracting attention from large tech companies. We all want to own a smart home, but sometimes language becomes a barrier in setting up IOT...
Here is a simple DC motor speed controller circuit that can be configured to control the sweep rate of automobiles’ windscreen wiper. The circuit comprises a timer NE555 (IC1), medium-power driver transistor BD239 (T1), high-power switching transistor BD249 (T2) and...
This alarm plays your prerecorded voice message. It is built around the readily available quartz clock. Take the buzzer out of the quartz clock and connect its positive terminal to pin 1 and negative terminal to pin 2 of...
In this series of four articles, fundamentals, as well as advanced topics of image processing using MATLAB, are discussed. The articles cover basic to advanced functions of MATLAB's image processing toolbox (IPT) and their effects on different images. Part...
AC switches are silicon devices that control AC loads directly connected to the AC mains. This means that the driving reference terminal of the AC switch can be connected to the Line potential. This circuit explains the need for...
In this project, we are going to make a smart OTP-based locking system as you can see in (Fig. 1). This smart lock can generate a new password every time you unlock it, which further enhances your security level....
  As water consumption and wastage increases day by day, water scarcity has become a growing concern around the globe. While some irresponsible people are overusing water and wasting it daily, a large population remain deprived of safe drinking water....
Op-amps require dual-polarity supply for proper operation. When working with battery supply, it becomes difficult to get dual power supply for the op-amps. Presented here is a simple circuit that provides ±5V from a 9V battery. Circuit and working The...
