I’ve been asked a few times – what is a diode? Well, a diode is an electronic component that conducts current in one direction and blocks current from flowing in the other direction.
If you want to learn and build your own inventions with electronics, you need to learn the basics of electronics.
Without a good understanding of basic concepts such as current and voltage, it's going to be hard (or impossible) to understand how different circuits work.
But it doesn't have to be hard. Do *not* confuse basic electronics with "all electronics theory that exist". A lot of books and blogs make this mistake. And it's discouraging for beginners.
Basic electronics is easy.
This page is a library of resources to help you learn the real basics of electronics.
A diode is a component that only conducts electricity in one direction. It is commonly used to convert from alternating current (AC) to direct current (DC). Several types of diodes exist. And it can be a bit confusing if you have never worked with diodes before. I would like to share the most standard types […]
A current limiting resistor is a resistor that is used to reduce the current in a circuit. A simple example is a resistor in series with an LED. You would usually want to have a current limiting resistor in series with your LED so that you can control the amount of current through the LED. […]
I love logic gates. They are what all digital electronics are based upon. You can make really awesome stuff with it! I was first introduced to logic gates when I was around 14 years old. I heard that computers consisted on ones and zeroes. But I didn’t understand what that really meant. So I asked […]
A voltage divider is a circuit that divides a voltage between two resistors. It’s extremely useful to know! If you know how the voltage divider works you can easily make sensor circuits or calculate values in a more complex circuit.
Yes, basic electronics is easy. As long as you don’t make it complicated ;) An electrical current is the flow of electrons in a wire. Electrons flow when you have a “closed loop” – a path from the negative to the positive terminal of a battery. For example if you connect a small light bulb […]
