This is the first basic LED circuit I built many years ago in my school days and had given me immense pleasure to see glowing LED. For building this circuit you only need four things: LED- 1; Resistor ...

Circuit Diagram and Explanation: The circuit Diagram of the high power LED driver is shown in the image below. As you can see the driver has nothing more than a LM317 IC and a resistor. The above ...

A basic LED driver PCB designed in OrCAD, based on a tutorial by Robert Feranec. This project includes schematic capture, PCB layout, and beginner-friendly design practices for creating a single-LED ...

Learn how to use LED circuits in your STEM projects with these four creative ideas. Make LED greeting cards, wearables, sensors, or games with simple materials and tools.

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

Light-emitting-diodes (LEDs) are solid-state devices with specific v-i characteristics. In this paper we study the basic requirement of the driving circuits and discuss the proper approach to driving ...

Figure 3 An alternative was to put the LED and resistor across the coil instead of the LED in series, which would cost just one extra resistor beyond the first idea. Further, some people are ...

By combining the conventional switched-mode power converters with advanced switched capacitor (SC) techniques, a plurality of single-switch current-balancing circuits is developed to drive multiple ...

It is a very simple circuit indeed! You can access the AtTiny85 software code using the following link. This is a great starting point to create your own LED patterns for the earring! Though the above ...
