In this simple but effective project, you will learn how to make a simple circuit using a 9-volt battery, LED, and pencil drawing. This project is a fun way to explore and learn about the science of ...

Here is the list of best LED based projects along with the circuit diagram, working and applications. LED – Light Emitting Diode. We are all very well know that LEDs are now playing vital role in many ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

I was puzzling over the classic bistable circuit and wondering if it was possible to expand it to any number of channels. And this is what I came up with. BTW: To make it more interesting (claims I), ...

LEDs are a staple component in most circuits. Using Ohm’s law, we can easily calculate the conditions for the theoretical lighting intensity we’re after. LEDs are a staple component in most circuits.
