LEDs are one of the most commonly used electronic components. They need careful handling, though, and can be damaged by too much current or voltage.
In this video I show how to connect up LEDs and how to work out the correct resistors to use with them, as well as reviewing the common type and specifications for them. I also show how to measure the voltage and current in the LED circuit and demonstrate a couple of examples, including an LED connected to an Arduino output pin. The last part of the video gives some tips on choosing and using LEDs.
In the following parts of this series I'll look at connecting LEDs in series or parallel and how to make sure you have suitable power for them to work safely and effectively.
