Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

Regular candles can be awfully boring at times. They can only produce one color and the flicker is so… predictable. They can’t even be controlled by an infrared remote control, not to mention the ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Hi there, and welcome to Part 3 of this soon-to-be-heralded mega-mini-series. In Part 1, we discussed the first vacuum tube diodes, moved on to their solid-state (semiconductor) descendants, and then ...
