Neo Pixel LED Code Breakdown!

Today I'm going to be going over some code segments from a recent video I made on using a neo pixel with Arduino. You can watch the video here: https://youtu.be/CPTLbmnqsGU

I plan to use this in a few other projects I have planned for Halloween! I hope you enjoy them and possibly build one yourself. Bur first I had to figure out how to use one with and Arduino. The great thing about the neo pixel line is the open source library which can be found here: 

https://github.com/adafruit/Adafruit_NeoPixel

Once you have the library you have quite a bit of starting code to work with. This is where I was able to find the building blocks for the four Arduino sketches I have created. Fade Color and Fade Color Change I found the base code online here: https://gist.github.com/fenihel/835719d8f4af0d545242898bcb6a86c4

I then edited this to include a delay that helped smooth out the fade effect. I then copied it for a second color and edited the setLightsToBrightness method to intake a set of RGB values which then allowed it to change colors when I swapped between sets of fades. 

This may not be the best way to perform this but it does work!

When it comes to RGB Values you can use a color slider like this:

To help get different colors based on what you want. The values mix together to make 1000's of colors for whatever you would like. This is very helpful especially if your looking to get a certain color for your project. This is a great way to get lighting on costumes!

The other two are based on the neo pixel library sample code but I removed the rainbow change section and applied different color values to make a red green change. The great thing about the library is these functions that it already has are easy to work with and change to meet your needs. With this I am hoping to make some very interesting projects with a much more in depth break down of the code. This video was meant to be just a quick overview of the Neo Pixel as well as a learning tool for myself to make much more interesting LED effects for later projects.

Until next time remember to stay Nerdy!!

CNC Flip Table pt.1

Hi All, This post is part of my recent video and if you have not seen it take a look:https://www.youtube.com/watch?v=nfm4ryxgsms This week I have been working finding a better way to store my CNC machine in my small shop which is in my garage. I have been wanting to do this for some time and finally I have had the chance to do it. Part of having a small work space means finding better ways to utilize the space available to maximize your efficiency. One issue with having a CNC machine is space consumption. When the machine is in use this is fine as the space is justified by production. But currently I am not in production mode and don't want to use up my premium space. So time to build a flip cart to hold the machine. This is only part 1 of a multipart video and blog series as I will be really fleshing this out to maximize the carts storage and functionality capability. But first thing is first do I build the cart from scratch or start with a good known base? The answer was a good k...

Clean Energy for the Future (New Wind Turbines!)

Image
 Hi All, This week I wanted to focus on clean energy. We all have heard about it with the world needing to find better ways to reduce our carbon footprint. This includes the adoption of EV's which we are pushing for but this is only one piece to an even larger puzzle. While EV's and other vehicle propulsion is great what about our energy infrastructure for our homes and businesses? Well we know about solar power, wind power, hydro electric and of course nuclear energy. These are all at the for front of our slow energy revolution. And while I would love to discuss each of these in this post there simply is not enough time to do so. For this post I am going to focus on wind energy.  Now everyone has seen these turbines before: They are common place almost everywhere. But there are a few problems with these units. First they are big so they take up a lot of physical real-estate, They also have lots of moving parts and are difficult to transport. So what can we do? Well we can red...
