I’ve since reconsidered, and now, I like hot glue because it is convenient and can be removed later if there is a need to check a connection or replace a part.
Using an Arduino Uno to calibrate an RGB LED strip.
The purpose of running this example is to determine what settings are needed to use the FastLED library. For this example I’m using an Arduino Uno. The Uno has a ground pin next to pin 13, so for convenience, I’m using pin 13 as a low-current Vcc for the RGB LED lights strip:
They are in games, decorations, shadow boxes, sign borders, torches, spotlights, and so on…

Now, I would like to discuss protecting your web server from becoming a victim to a potentially malicious attack.
