Ah, life as an electrical engineering student...becoming an engineer can be intimidating - if you've looked into it at all, you've heard the horror stories about electrical ...

Learning and understanding a different base-numbering system has one very large similarity to learning a new language. You need to truly understand the language/base system you ...

In our previous tutorials about diode, we have discussed how a diode operates theoretically. A diode can be used as rectifier in which it could be a half-wave or a full-wave ...

Hi there! This is an auspicious moment. In this microcontroller tutorial, we start applying what we’ve learned and make things happen. This is our first tutorial devoted to ...

This is the last microcontroller tutorial before we load some code on the microcontroller and start actually doing things! It’s very exciting. In this tutorial, I will provide ...

Hi again and welcome back! In this tutorial, I will provide more detailed information about the PIC10F200 microcontroller so you understand exactly what we’re doing and why. ...

While the microcontroller is the brains of a project, there are a lot of other things required for a functional circuit. So, let’s first figure out what we will need to develop ...

These microcontroller tutorials come from the idea of making some cool things using the most simple and primitive microcontroller possible. So, if you want to learn about ...

The last time we discussed diodes, we learned about its basic structure and how forward biasing allows current through the pn junction. This time, we are going to discuss about ...

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 ...

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 ...

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 ...
