One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is: “Subtract 2 V from the supply ...

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 ...

The project is originally designed as LED calculator but the addition of a rotary encoder to set the target system voltage results to adjusting the LED brightness using the potentiometer. By turning ...

VCC has designed a series of LED sockets that feature a built-in current limiting resistor to provide optimal LED performance. VCC has designed a series of LED sockets that feature a built-in current ...
