- Few things hurt your ego more than spending an afternoon fighting your code, only to realize hours later that a bad component was causing all of your problems. Electronic components are mass produced. Most production facilities have some QA process components go through before they leave the factory, but bad components do slip through. After the components leave the factory and spend months in transit, additional components will fail. Between components that are dead on arrival, and those that fail under your watch, you will encounter bad components. You can test for these with a Multimeter. A Digital Multimeter measures voltage and resistance. Digital simply means the information is presented digitally rather than through an analog gauge. Next to your soldering iron, this is the most important tool in your repertoire. Multimeters can cost thousands of dollars and are often giveaway or free with coupon tools on the low end. While the expensive variants offer lots of functionality…
