Need some indicators? We are big fans of these diffused white LEDs, as featured in the LoL shield. They are really bright so they can be seen in daytime, and from any angle. They go easily into a breadboard and will add that extra zing to your project.

• Pack of 25 diffused white LEDs
• 3mm diameter
• 3.0-3.4V Forward Voltage, at 20mA current
• 500+ mcd
• The LEDs tend to be in the ~5000K temperature but there may be slight variations between batches. Each bag of 25 has the same color temperature LEDs but multiple bags may vary in the 'color temperature'

If you need some help using LEDs, please read our "Introduction to using LEDs" tutorial for any electronics project.
