In the field of DC-DC Converters, A single-ended primary-inductor converter or SEPIC converter is a type of converter that uses a boost type control topology to step up or step down the input voltage. After reading this, the first question that will come to your mind would be, is it like a glorified Classic Buck-Boost Converter? The answer is yes and no. A classic buck-…
Text-to-speech (TTS) is a type of speech synthesis program that is used to produce a spoken sound version of the text, such as a document file or a Web page. TTS can make it easier for a visually impaired person to interpret computer display information or can be used to improve the comprehension of a text message. Other than that, it can be used to make your robot speak or…
The increasing concentration of carbon dioxide in the air has become a serious problem now. According to the NOAA report, the ozone CO2 concentration has reached 0.0385 percent (385 ppm) and it is the highest amount in 2.1 million years. This means that in one million particles of air, there are 385 particles of carbon dioxide. This rising level of CO2 has affected the…
IR (Infrared) communication is simple, low-cost, and widely used wireless communication technology. IR light is somewhat similar to the visible light, except that the wavelength is slightly longer. This property of IR makes it undetectable to the human eye and perfect for wireless communication.
There are lot of applications where you need to decode…
I started this project in order to get rid of various remotes at my home and build something single which could incorporate features of all of them. I got this idea when I saw one of my friend’s mobile phone with built in IR blaster, at that time I decided not to buy a similar phone rather make my own device which should be compatible with my existing handset. So here we are…
Relays are common in many switching circuits where controlling (turning ON or OFF) an AC load is required. But due to the electromechanical characteristic, a mechanical relay has a self-life, and also it can only toggle the status of the load and cannot perform other switching operations like dimming or speed control. Apart from this, an electromechanical…
Be it a boring afternoon, a monotonous job or a lonely long drive FM radio stations have always kept us entertained. While on the contradictory it should also be agreed that sometimes these FM stations get very boring with the RJ blabbering irrelevant stuff or some bugging advertisements and that might have kept you guessing why you can’t have your own FM Broadcast station…
QR code (Quick Response code) is a type of matrix barcode that contains information about the item to which it is attached, like location data, identifier, or a tracker that identifies a website or app, etc. It is a machine-readable optical label in the form of a 2D image with a unique pattern. To learn more about QR codes and how to generate a QR code, follow our previous…
If you are an electronics hobbyist then you must have heard about the 555 timer IC and its 3 popular circuits viz. astable multivibrator, bistable multivibrator, and monostable multivibrator. Apart from these, there are other popular circuits like 555 timer IC as a switch and police hooter that we have talked about previously. Adding to the list,…
Charlieplexing is a technique of controlling many LEDs using a few I/O pins. Charlieplexing is same as multiplexing, but it uses the tri-state logic (high, low input) to reduce the number of pins dramatically and to gain efficiency over multiplexing. The Charlieplexing technique is named after its inventor, Charlie Allen, who invented the technique in 1995. We previously…
This will be the fifth tutorial in our PIC Tutorial Series, which will help you to learn and use Timers in PIC16F877A. In our previous tutorials, we had started with Introduction to PIC and MPLABX IDE, then we wrote our first PIC program to blink the LED using PIC and then made a LED Blinking Sequence by using delay function in PIC Microcontroller. Now let us use the same…
In this project, we are going to develop an RFID and keypad based Security system. This project is implemented by using 8051 microcontroller. RFID Tecnology (Radio Frequency Identification and Detection) is commonly used in schools, colleges, office and stations for various purposes to automatically authenticate people with valid RFID tags. Here we will check the RFID…
