Hi again! It’s time for a new tutorial! Today, I’ll tell you how to receive and process the signals from the IR remote. Basically, the task will consist of two parts. In the first ...

Welcome back! I hope your first experience with the Assembly language was pleasant, that it got you excited, and now you are looking forward to more and more interesting programs. ...

Have you ever asked yourself how this small electronic device, an LED, emits light? Compared to the much less efficient incandescent light bulb, which produces light by converting ...

In our discussion about how an RGB LED works, we’ve mentioned that an RGB LED is basically an LED package with three internal LEDs (red, green, and blue) inside it. In order to ...

While LEDs may be everywhere now, that obviously wasn't always the case. So how did we go from no LEDs to LEDs in nearly everything on the planet? As we researched it, we were ...

We took apart two LED lightbulbs, a CREE LED bulb from 2014 and a Philips bulb from 2018, and compared their build quality, the electronics, and their overall design. It was ...

Ask an Electrical Engineer is a series where frequently asked questions from non-engineers will be answered by an engineer. For this video, our main topic is all about LEDs (Light ...

Dimming is the process of varying the light output of a light source. This is done to set the ambience or to save energy when full light output is not really needed. Most of the ...

Ask an Electrical Engineer is a series where frequently asked questions from non-engineers will be answered by an engineer. For this video, our main topic is all about LEDs (Light ...

We've discussed a lot about LEDs like how it works in a semiconductor level, its pros and cons, and how an individual LED can be dimmed through constant current reduction (CCR) or ...

Why do we need a resistor for an LED? Once you pass the forward voltage, a slight increase in voltage makes a huge increase in current. You don’t wanna blow things up!

LEDs are better than other light sources in most applications. While they are more efficient, there are a lot more things to consider when buying a lightbulb than just how much ...

I have to admit, I’m biased. I think LEDs are awesome. But, really, the reason I’m biased and love them so much is because they’re just so cool. I’ve found that as I replaced the ...
