The mystery of adding LED lights to a modern BMW with CAN Bus (Controller Area Network) electrical system is easy to resolve. The “smart” CAN Bus smells a rat when you pop in an LED brake light or ...

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 ...

The ubiquitous LED continues to expand frontiers and applications with a plethora of sizes, colors, and output lumens. Flashing LEDs that incorporate internal electronics for oscillation offer ...

Infrastructure projects like the Tokyo Gate Bridge are now turning to LED lighting because of its economical and environmental advantages. But these devices still need the right current-limiting ...

In my previous column, we covered quite a lot of ground, starting with the first vacuum tube diodes, moving to their solid-state (semiconductor) descendants, and progressing to their light-emitting ...

The STM8S001J3 is an 8-bit microcontroller that offers 8 Kbytes of flash program memory, plus an integrated true data EEPROM. It is referred to as a low-density device in the STM8S microcontroller ...
