Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

Diodes are essential components found in electronic circuits. They allow current to flow in one direction while blocking it in the other. With time and usage, diodes can become defective, leading to ...

Here is a handy zener diode tester which tests zener diodes with breakdown voltages extending up to 120 volts. The main advantage of this circuit is that it works with a voltage as low as 6V DC and ...

Abstract: In general, measuring electronic circuits can only use ordinary measuring tools or manually. But as technology develops, measuring electrical circuits does not only use manual tools but can ...

The diode is a fundamental component you must understand if you want to grow your electronics prowess. So today, we’re going to take a quick look at what a diode is, then look at 4½ uses for a diode ...

Thermal imagers are invaluable to help quickly troubleshoot electrical equipment, panels, and transformers but electricians and maintenance technicians often do not have access to one when they need ...
