Suppose you intend to design a robot or a toy car, the knowledge about motors is paramount. A very cost-effective and easy way to control these motors is to use an L293D driver motor shield. Better still, use it in an interface with a microcontroller like Arduino. Among the oth

Car Alarm Did you know that the United States alone experienced a hike in the national rate of motor vehicle theft within the last 30 years? This report from Statista also revealed over 240 cases per 100,000 population. What does this mean? It means that your car is a n

Microcontroller on board Source: Wikimedia Commons Before you dive into the world of embedded electronics, you need to understand what it takes. For instance, this field involves writing your codes. And it’s almost impossible to do this if you don’t understand microcontr

An electronic circuit is simply a path for electrons. Circuits are passages for electric current to flow. Hence, the bulb needs a closed path for the current to pass to light up.  Electrical developers use circuit boards in various electrical devices ranging from flashligh

Noise and interference are common when dealing with electrical devices because different circuits produce varying signal frequencies that clash. Such issues are prevalent in communication devices, which get easily affected by power lines. If you are experiencing such issues, there

Flip-flops or latch circuits majorly help to design registers and counters that store data in a multi-bit number form. However, the register devices often need many flip-flops circuits connected sequentially to each other. The sequential circuits must then go through triggering pr

First off, let’s be clear, Op-Amp means operational amplifier. And the device is a high-gain electronic voltage amplifier (DC-coupled). Plus, it has a single-ended output and distinctive input resistor. Also, it’s the Analog electronic circuit’s basic building block. Further

Are you thinking of building a high DC voltage test equipment? Such a device is necessary for testing or building electronics and appliances that require high DC voltage, such as microwave ovens and cathode ray tubes. While it is possible to use a step-up transformer and rectifier

Security is one of the few things that is a priority regardless of where you are in the world. As a result, security check-in in most public and private places or areas is a given. In the case of security officers, they either use walk-in metal detectors or wands. Metal detectors

A relay is a switch with an electrical circuit operating it. Since it is a circuit, it has a series of input signals and control signals. Significantly, it works by receiving an input signal from connected input power sources which act as standard switches. This article will walk

Relay drive is an electronic component you’ll encounter in numerous electronic circuits and electrical devices. The different relay types particularly benefit mains AC load switching or high-power transfer circuits a great deal. Not only that, but they are also cheap and pra

Are you interested in learning or making digital circuits such as the ones found in computers, communication equipment, and other similar types of systems? The first thing to look at should be the transistor flip flop. The fundamental building blocks of flip flops are logic gat

PWM (Pulse Width Modulated Inverters) served as a replacement for older types of inverters. For this reason, they have a wide range of real-time applications. In most cases, companies use them in the creation of power electronic circuits. Pulse Width Modulated Inverters usually us

Isn’t it frustrating when you insert a button cell battery into a gadget only to get an error message? Don’t worry. You aren’t alone.  Since several battery types look similar, most people can’t tell them apart. It’s also challenging to remember the battery names. Battery CR2025 v

An LM338 integrated circuit is part of the LM-series ICs made by the National semiconductor. LM338 application circuit is similar to LM350 or LM317 in terms of easy usage and few components. However, LM317 has a lower current than LM338. In today’s post, we’ll discuss

High dynamic signals will always pose a problem to designers. They are necessary for echo-ranging devices such as radar or sonar systems. But in such systems, we need high gain for the low amplitude signals and vice versa for high amplitude systems. Also, another problem with the

To keep you up to date with impactful information on technology and engineering, we will look into the 4047 IC.  The 4047 IC is one of the most popular inverters in the world. Furthermore, in some countries where electric load-shedding has proven to be an issue, the 4047 IC has

Mist makers and foggers have become an integral part of the entertainment industry, be they movies, concerts, or even adverts. You will see mist appear at some point, either when creating suspense or introducing an act. Slowly but surely, foggers have found their way into other in

Good music, as they say, is food for the soul. Operational amplifiers form an integral part of audio systems, and damage to it affects the audio output. Therefore, if your sound system produces noise feedback, there are a couple of possible solutions. One of them is to use a NE553

We are all aware that we have technology and circuits everywhere in our surroundings. We use a 24v to12v converter circuit in very many appliances that need stepping-down of current. Understanding how these converters work and their benefits are essential if you require a voltage
