We all know about voltmeters. Besides multimeters, there are some panel meters that show voltage, current, etc. Making such an AC voltmeter is sometimes becomes very helpful. Here in this article, we are going to learn how we can make our own single-phase AC voltmeter using a PIC16F76 micro-controller and Read more
When you are working with electronics, especially power electronics you must have to measure line frequency. But in most cases, people do not have a frequency meter. If you knew how to make a frequency meter in a very easy way, you would make one for yourself. Here in this Read more
Like the high voltage AC meter, we can use the same Op-Amp circuit to measure high voltage DC voltmeter. In this article, we are going to learn how to make a high voltage DC voltmeter using a micro-controller and Op-Amp circuitry. How to sense high voltage floating DC with Op-Amp? Read more
