National Instruments (NI), is probably best known for the LabVIEW software and modular instruments. In the past few years, they have introduced more innovative test and measurement products than any other T&M manufacturer, at least, in our opinion.

Their latest box is called the “VirtualBench.” It’s a lab’s worth of equipment in a single box at a reasonable price. It combines a DMM, Oscilloscope, Logic Analyzer, Power Supply, and Function Generator into a single box.

What was the first electronic component you played with? It was probably a LED. They’re fun to blink in patterns or learn to fade. Most projects (and products) use them for useful indicators.

LEDs add magic to every electronics project. Often not understand is what else you need to make that LED work correctly. Learn what current limiting resistors do for LEDs and watch what happens when you don’t use one.
