You don't have to worry about adding a resistor to an LED if you get an LED with a built in resistor! This pack of 25 yellow 5mm LEDs will help alleviate any frustrations you've had with accidentally burning them out by having a resistor in the diode itself. Each LED has an operating voltage range of 2.0V to 5V to help make your next project shine!
Each pack of these LEDs are conveniently bagged in reusable ESD safe packaging to make sure nothing accidentally gets damaged before you are able to use them.
If you look closely at the image below, there is a small, black square IC on the post to limit the current on these types of LEDs.
For more information, check out our LED tutorial.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

When building on a solderless breadboard or soldering on protoboard, component placement can be difficult enough with limited space and limited tie points, working in the resistors for your blinken lights makes it even worse. Being able to connect these straight from signal to ground helps immensely. Will still use leds with matched resistors for final boards, but for prototyping, these are awesome!
