A maker shared an electronics project on Digikey that explains an automatic system for recognizing and organizing resistors using an Arduino Uno Q. Zach Hipps did the work and looked for methods to ...

With surface-mount components quickly becoming the norm, even for homebrew hardware, the resistor color-code can sometimes feel a bit old-hat. However, anybody who has ever tried to identify a random ...

Hans Rosenberg] has a new video talking about a nasty side effect of using resistors: noise. If you watch the video below, you’ll learn that there are two sources of resistor noise: Johnson ...

It’s not easy being a current-sense resistor: so much is expected of this basic function of determining current flow by simple measurement of voltage across a known resistance, then applying Ohm’s Law ...

One of the standard methods used to measure load current is to insert a low-value resistor in the load line and sense the voltage across it, Figure 1, followed by an analog or digital implementation ...

How and why sub-milliohm chips warrant consideration as a separate class of component. Strategies for smart component selection, layout design, inspection and soldering process control. While ...
