Electronics explained in a simple way
In this tutorial, you’ll learn how to build an automatic night-light that turns on when it gets dark. It’s a simple circuit that you can build on a breadboard.
This circuit shows you how to do it with an LED. But you can use the same principle to turn on bigger and brighter lights too.
Find the breadboard diagram and parts list below the video.
[Read more…] about How To Build An Automatic Night-LightElectric current is what you get when electric charge moves around a circuit. It’s pretty simple when you finally get it. But there are some common pitfalls that can give you the wrong idea when learning.
And if you don’t know what current is and how it works, it’s a huge source of confusion when learning electronics.
My goal is that after reading this article, you’ll understand what current is. And you’ll understand that a resistor must have the same amount of current going into it as going out from it.

Use the breadboard diagram or the video below to see how to connect everything.
The difference between Alternating Current (AC) and Direct Current (DC) is simple: AC vs DC comes down to in which direction the current flows. AC is a current that alternates its direction. It goes back and forth continuously. DC is a current that flows in one direction.
Current flow in a DC circuit:
I put together this Voltage Unit (VU) meter using LEDs on a breadboard the other day. It only has 4 LEDs, but can easily be expanded to more:
It’s basically a simple display for showing a value. It’s originally for showing signal level in audio circuits, but there’s no reason you can’t use it to show temperature, rain intensity, light level, or whatever other value you are measuring.
