One of the first things you learn in electronics is how to identify a resistor’s value. Through-hole resistors have color codes, and that’s generally where beginners begin. But why are they marked ...

Messing around with Arduino can lead to some fun projects — like simple electronic games, lighting or audio manipulation, or even gesture controls for other devices. However, you'll need the right ...

Here’s a tip from a wizened engineer I’ve heard several times. If you’re poking around a circuit that has failed, look at the resistor color codes. Sometimes, if a resistor overheats, the color code ...
