We use a lot of different components in our electronics devices but diodes are usually the first non-linear component people use in a circuit. Whether it’s because they’re turning ...

Hi there! After the last two tutorials, we are confident about dealing with buttons. Today, we’ll expand this knowledge and learn how to check the state of the several buttons at ...

In our discussions about diodes, we have learned that a PN junction is a boundary formed between a P-type and N-type semiconductor when they are combined. When a PN junction is ...

Ho! Ho! Ho! Christmas is coming soon, so it’s time for some magic. And I’ll show you some real magic today. As we all want to feel relaxed before the Christmas holidays, I won’t ...

Have you ever wondered why we operate a Zener in reverse bias unlike normal diodes that are operated in forward bias? This is because Zener diodes are meant to ‘break down’. Most ...

Hi again! After the meaty last tutorial, I think it would be good to rest a bit and consider something relatively easy and short. Also, I haven’t provided a homework solution this ...

Hi again! This time we’ll put the LEDs aside and try something new. We will play music using a buzzer. Interestingly, some of the basic concepts are the same as with the LEDs but ...

Hi there and welcome back! In tutorial 6, we made an LED blink and this time, we’re going to control the LED again but, unlike last time, we will not just blink the LED but ...

A transistor is an electronic device that can be used as an amplifier or as an electronic switch. Its ability to amplify a signal or to switch high power loads using a small ...

Welcome to the second part of asking engineering jobs, where we talk more about the jobs and career opportunities for electrical engineers. With that, let's get back into it.

Welcome to Ask an Engineer where we are going to talk about jobs, this time. Careers, electrical engineering jobs and careers, things like that. And so in this, basically, we have ...

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. ...

Welcome to Part Two of Ask an Engineer - College Edition. And here I'm going to continue answering all those questions that we have received about what life is like going to ...

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 ...
