In our previous articles, we learned how to make an AC voltmeter and how to measure high voltage AC voltage. In this article, we will learn how to make a high voltage AC voltmeter. Yes, you can measure 500V+ or Read more
Measuring high voltage AC is not safe just with a resistor voltage divider. Or sometimes, we can not connect one terminal to the GND of the measuring circuit. Sometimes, we need to measure a floating high voltage. In this article, Read more
After making a DC voltmeter in our previous post, you may be looking for an AC voltmeter. Yes, in this article, we’ll learn how to make an AC voltmeter using a Seven Segment display and PIC16F73 micro-controller. Many people just Read more
A DC voltmeter can be used in many devices, even sometimes it becomes a must having feature for a device. In this article, we will learn how to make a DC voltmeter with Seven Segment and PIC micro-controller. So let’s Read more
Seven Segment display is one of the most common LED/LCD-based displays which is used in many meters, clocks, info-display type devices. In this article, we’ll learn how to interface the Seven Segment display especially that one that has multiple digits Read more
Irrigation is important for our farms whatever it is on large scale or on a small scale. Due to lack of rain and water flow, lots of crops damage each year. Even in your home plant pots need to do Read more
A wattmeter is an useful meter to us. We can measure the power of the load with a wattmeter. You can buy this expensive meter but did you know that you can make one for yourself? In this article, we Read more
Hi, you can generate a pure sine wave just using an Op-Amp. It is very simple and can be used in many applications. In this article, we are going to learn how to generate a pure sine wave using an Read more
Maximizing power output from solar panels is essential for efficient energy utilization, and this is where an MPPT (Maximum Power Point Tracking) Solar Charge Controller comes into play. In this article, we’ll explore how an MPPT Solar Charge Controller works Read more
In this article, we are going to make a complete project with RFID. Many students made this project and submitted it to their institute as their final year project. You can make this project for your final year project too. Read more
