LEDs are probably the most-liked elements by all beginners maybe even by everyone involved in electronics projects. One of the most important factor to use them properly is to connect them the way they should. Of course, usually you need to use a resistor in order to limit the current and avoid burning your LED, but that's not what I am going to write about in this instructable. I want to talk about even more basic thing: checking the LED polarity. In electronics you can find various components, we can divide them into polarized ones (LEDs, electrolytic capacitors, transistors, microcontrollers and many others) and ones that don't have polarity (resistors, coils and other). Polarized component means that it has to be connected in a specific way in order to work. Connecting it the other way may damage it, it may even explode (electrolytic capacitors) or your circuit will just not work properly. So polarity is very important as you can see.
