Time will always be“of the essence” for professional engineers and amateur enthusiasts alike. This can certainly be said about the process of designing circuits involving Light Emitting Diodes (LEDs).

Here is an excellent resource, certainly worth bookmarking if you are creating your own LED lighting systems - the LED series/parallel array wizard. It describes itself: The LED series/parallel array ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design ...

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 ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...

High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...
