Chances are, you have used the continuity mode of your digital multimeter. But how much do you understand about how it works? In this video, we break down how the mode works, what …

Generating signals with a waveform, function, or arbitrary generator lets you test all kinds of circuits. Learn how to get a function generator to output a signal, the 3 types of …

Logic analyzers capture digital signals and then display a waveform or list. Serial busses like I2C, SPI, or UART (Serial) can be decoded or triggered on when there are problems in …

A spectrum analyzer displays signals in the frequency domain. To use one, you only need to know about four controls: reference level, center frequency, and resolution bandwidth. In …

During the Bench Power Supply basics video, I made use of my electronic load. An electronic load can sink current from power sources such as power supplies or batteries. Loads are …

A bench power supply makes powering circuits easy and safe. Learn how to adjust basic controls like voltage. Finally, see how “current limiting” works (and why you should use it.) …

One of my early hobbies as a kid was collecting baseball cards. At every card show, I was on the lookout for the 1989 Ken Griffey Jr Rookie card, #1, from Topps.My collecting craze …

Rob ’linear’ Arnold has put together a fantastic LED Series/Parallel Wizard. Not only will it calculate the current limiting resistor you need, it will draw a circuit diagram, and …
