Nowadays, Security system is one of the most researched fields and with increasing security threats, companies are launching new smart security products to combat these threats. IoT is an added advantage in this field which can automatically trigger an event, like calling the police, fire brigade or your neighbor, in case of any emergency. We previously built […]

This is an article from the sequence of our articles in which we have been discussing about inrush current. We have already covered the basics of inrush current and the various types of Inrush Protection circuits in our previous articles. The most common method of inrush current protection is by using an NTC Thermistor, so in this article, we will
Current Source and Current sink are two major terms used in electronics design, these two terms dictate how much current can leave or enter a terminal. For example, the sink and source current of a typical 8051 Microcontroller digital output pin is 1.6mA and 60uA respectively. Meaning the pin can deliver (source) up to 60uA when made High and

If you are thinking about building a simple, cheap, and moderately high power amplifier circuit that can deliver up to 50-watt peak RMS power into a loudspeaker, then you are in the right place. In this article, we are going to use the most popular TDA2050 IC to design, demonstrate, build, and test the IC
The LA4440 is a very popular dual-channel audio amplifier commonly used to build high power audio amplifiers. The IC is known for its high power, easy availability and cheap price which makes it popular amongHome Theatre and Car Amplifier Systems which operate on 12V. Hence in this article, we will learn how to build a High-Power Stereo Audio Amplifier using

Who does not like the rumbling tone of a distorted electric guitar? It is a key part of many important genres of music, especially in blues and rock music genres and is also frequently used in hard rock, metal or the punk music genre. In this project, we will build a basic distortion pedal for guitars using
Often times, we need to control bass, treble, and volume of our audio signal before passing it through amplification stages to prevent sound distortion. The circuit that amplifies the audio signal before it enters the main speaker amplifier is called an Audio Preamplifier. The use of an audio pre-amplifier ensures good audio quality and provides options to modify

For microcontrollers, an LED blinking program is equivalent to the “hello world” program. In our previous tutorial, we learned how to get started with STM8S103F3 Development Board and how to set up the IDE and compiler to program our STM8S controllers. We have also learned how to use the standard peripheral libraries, and how to compile and
There are lots of microcontrollers available from reputed companies such as PIC, Texas Instruments, ST and the list goes on. But when we differentiate those microcontrollers with form factor vs features vs price, it gets hectic to choose one. However, nuvoton is a Taiwan based semiconductor company that was spun-off as a Winbond affiliate in
