In our previous tutorial Getting Started with the RASPBERRY PI ZERO, we had an overview Raspberry Pi zero W and setup the Pi Zero. In this tutorial we are going to design a simple LED circuit and ...

The basic circuit illuminates up to ten LEDs in sequence, following the rhythm of music or speech picked-up by a small microphone. The expanded version can drive up to ten strips, formed by up to five ...

Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...

AC LED driver circuits are overly popular due to the advancement of High current white LEDs. We already made a Transformerless LED driver circuit previously, but in that circuit, we used a dedicated ...

In this project we are demonstrating how 5 I/O pins of the mighty AtTiny85 microcontroller can be used to control 20 LEDs - one by one! The method we will be using here is called charlieplexing. The ...

High-brightness LEDs, with independent delay and duration, find use in a visual-inspection application. This circuit is not complex, but it saved the day in an application involving visual inspection ...

[Alberto Piganti], aka [pighixxx] has been making circuit diagram art for a few years now, and has just come out with a book that’s available on Kickstarter. He sent us a copy to review, and we spent ...

In this project we are introducing a simple circuit and code that will allow you to create fully programmable and customizable earrings. We are also leveraging the mighty power of the ATtiny85 ...
