Episode 8: LEDs and Current Limiting Resistor

What was the first electronic component you played with?  It was probably a LED.  They’re fun to blink in patterns or learn to fade.  Most projects (and products) use them for useful indicators.

The most common mistake is to use a LED without a current limiting resistor.

For this video, we look at how LEDs and Resistors work individually.  Then we hook them up together in a simple circuit.  

We even go into the lab to get help from a couple of multimeters to see what happens when you do and don’t use a current limiting resistor.
