Resistors are the most commonly used component in electronics, as their purpose is to create specified values of current and voltage in a circuit. Since there's so much to understand about them, being ...

Many times, the need arises to interface single-supply analog-to-digital converters (ADCs) and comparators to real-world signals like 5 V. Of course, it's possible to condition the signal using ...

This paper dial makes selecting current limiting resistors a snap. [Giorgos Lazaridis] came up with the tool, which he describes in detail in the Worklog tab of his writeup. If you want one of your ...
