All embedded lovers are familiar with multimeter which a great tool to measure voltage, current, resistance etc. A multimeter can measure them easily. But sometimes we need to measure inductance and capacitance which is not possible with a normal multimeter. There are some special multimeters that can measure inductance and capacitance but they are costly. We already built…

Almost all types of sensors and transducers convert real world parameters like light, temperature, weight etc into voltage values for our electronic systems to understand it. The variation in this voltage level will help us in analyzing/measuring the real world parameters, but in some applications like biomedical sensors this variation is very small (low-level signals) and…

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words…

Pulse Width Modulation (PWM) is a technique that varies the width of a pulse while keeping the wave frequency constant. The PWM technique mainly used to control the brightness of the LED, speed of DC motor, controlling a servo motor, or in other cases, where have to generate an analog signal using a digital source. We explained the PWM in detail in the previous article.…

A few years back, if someone were to tell me a watch could not only tell time but can also measure the heart rate and track calories, I would be blown away by it. Today more than a million people, including me own a wearable fitness tracker and it is forecasted that the market for wearable devices would reach $57,653 millions by 2022. From smart glasses to Diabetes…

There are a large number of injuries resulting from electrical shocks especially while maintaining and repairing electrical lines and towers. It is very difficult to isolate and check the presence of voltage in the wires without cutting it. A contactless voltage detector could come in very handy when dealing with such situations to be sure about no presence of voltage…

Servo motor works on the principal of Pulse Width Modulation (PWM) and its angle of rotation is controlled by the duration of the pulse applied to its control pin. Here in this tutorial we will control a servo motor with ATtiny13 microcontroller using PWM technique. So before going any further we will first learn about PWM, Servo Motor and how to program ATtiny13 with…

Blynk is an easy-to-use IoT platform using which you can easily build graphic interfaces for all your projects by simply dragging and dropping widgets. But the issue while using the Blynk app is the latency and limited energy. This problem can be solved by using a Blynk local server. Blynk local server provides unlimited energy and reduces latency.

Various mosquito repellent solutions like coils, liquid vaporizers, and creams, all have possible adverse effects to health. Then there are electronic mosquito repellents available in market which are equally efficient and relatively safer. The concepts of these mosquito repellers are simple and we can build a simple mosquito repellent circuit at home easily by using 555…

India being a sports-loving country loves to watch sports in a group where the whole neighborhood comes and enjoys the sports together, be it cricket or football. But doing so, one of the problems we face is that the scoreboard on the bottom of our television screen becomes very small and hard to read. So, today we are going to build an IoT and Arduino-based IPL…

In this time of the Corona pandemic, elevators have become a high-risk place where everybody touches the same buttons. At many places, people have discovered tricks to prevent contact with elevator buttons like using a pumping paper, toothpicks, or sanitary tissues for pressing the lift buttons.

So in continuation of our previous Corona safety…

Any electronics projects enthusiast has to first familiarize themselves with basic electronic projects. This includes trying to build simple devices and circuits using components like resistors, LEDs, diodes, transistors, etc. This forms a firm foundation in handling electronic components and helps to build complex projects later. Once familiar with the basics, one can move…
