In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

[Henryk] just sent us his latest episode of simple LED circuit puzzles. In front of the camera he solders one pin of each of the 3 LEDs to a different switch. He then puts the three assemblies in his ...

To lower BOM cost and board space requirements, the single-chip LED driver eliminates the need for an external MOSFET and current-sense resistor. It integrates an I 2 C communication interface that ...

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 ...

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 ...
