Zero-Crossing Detector Circuit A zero-crossing detector circuit is a useful application of an op-amp as a comparator. This electronic circuit precisely identifies when an AC waveform transitions through zero voltage, tracking the changes in the sine waveform from positive to negative or vice versa while it crosses zero voltage. It can also be used as a square wave generator. They have many… |

How to Build a DIY Oscilloscope using Arduino UNO Minima? When working with electronics, a multimeter can tell you the voltage at a particular moment, but it cannot show you how that voltage changes over time. To observe these changes and understand what's happening inside a circuit, we need an oscilloscope. But instead of investing in a dedicated instrument, what if we could build a simple one ourselves using a… |
