I once worked with an engineer that often checked his resistors with a multimeter before use. I just assumed that he was just being careful (certainly more careful than I…). Then one day, he asked me ...

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 ...

Some people look at a venerable resource like resistor color code charts and see something tried and true, but to [Andrew Jeddeloh], there’s room for improvement. A search for a more intuitive way is ...

A resistor has 4 or 5 color codes generally, of which the last color code indicates the tolerance and the rest gives the actual value of the resistor. This code does not look into the tolerance. The ...

A resistor is an electrical component that implements resistance as a circuit element. So, identifying the value of resistance from the color codes of resistors is very important. Calculating the ...

Abstract: This paper proposes a real-time video analysis algorithm to read the resistance value of a resistor using a color recognition technique. To achieve this, firstly, a nonlinear filtering is ...
