Taking what I've learned about LED color mixing and Python, along with our LumiDrive LED Driver and LuMini LED Ring, I set out to create a light ring for macro photography that surpasses all others.

Last week, we took a look at using the digital pins on our new LumiDrive LED Driver. This week, we'll play with the analog pins, and see if we can't put something together using both!

If you're looking to try coding in Python, especially as it translates to the world of physical computing, the SparkFun LumiDrive is a great way to get started.

Technology and Art

Which came first, the function or the form? Regardless of the course your build takes from start to finish, there's no reason it can't be seen as both technology and art.

With the speed that technology changes and advances, products can't be expected to remain on the market forever. But what happens when a product's retirement interferes with your project?

Technology is making it easier and faster to do business, share information, and even argue with strangers around the world, but I believe there's more to it than that.

Chances are, you may never use all 16 million colors available to you with your RGB LEDs. But whatever colors you use, you should know how to smoothly fade from one color to another. And thanks to the wonders of math, now you can!

As makers, the more avenues of inspiration we have, the broader our library of projects will be. From the obvious to the unusual, inspiration can be drawn from almost anywhere.

It's time to bounce that old tennis ball out of your garage, and up your game with this simple project that lets you know exactly where to stop when pulling in to your garage.

Let's face it, as much as we love Arduino, there are some things it just can't do. To branch out, let's take a look at a little bit of Python.

Happy Halloween!

Halloween is made for makers. Whether your thing is an over-the-top, automated yard display, an amazing cosplay costume, or a beautifully carved pumpkin with an RGB LED light show emanating from it, this holiday lets us build things not because they're practical or necessary, but because they are fun!

With just a handful of parts and a couple of hours of work, you can easily repulse all of your co-workers at this year's office Halloween party!

What type of proximity sensor is best suited to your next project? We've put together a Proximity Sensor Comparison Guide to help you choose the right tool for the job!

This week, we take a look at the amazing new Xbox Adaptive Controller, and throw together a ridiculous project that barely scratches the surface of its capabilities.

Thanks, Othermill!

Great customer service fixed our registration issue.

  • Rats, I did say byte, didn’t I? Sorry, that one’s totally on me. It should be Megabit per second. Good catch, thank you!

  • YES!

  • I love a good project that stems from necessity, and yours is a great one! And I completely understand the whole “if we can see a wire and a battery, and heaven forbid, a CIRCUIT BOARD - it MUST be an explosive device!” mentality. I want to bring a fully assembled BigTime Watch to a friend back east, but I know if I try to fly with it, I’ll wind up in TSA jail!

  • It is definitely the same for me. My personal project stove has about fifty back burners, and maybe two or three at the front. I also tend to complete a project through proof of concept - hey look, it works! - the then leave it not quite finished as I jump to the next idea.

  • Glad you like it! The plan is to continue to take our components, and build them into practical projects like this. Hopefully it can inspire people to come up with ideas of what they can create next, once they’ve mastered the basics.

  • Thank you for that, and it absolutely doesn’t feel like an attack at all. With most projects I do, even once it’s up and running, I always feel like improvements could be made to my code. (That’s especially true when pushing to meet a deadline, as is the case with every one of my posts.) If I recall, I think I kept stopLimit as a variable in case I had time to add a stopLImit Up and stopLimit Down button as inputs to more easily adjust that distance for the user. But if the user is a maker who’s going to be putting it all together themselves, they could just as easily change the #define STOP_LIMIT number within their own code. Thanks for the feedback!

  • Absolutely! If I had ten more minutes before this was due, that would have been the first addition I would have made to the code.

  • Thanks! And I’m not that young - pretty sure the first time I went to Disney World, it was still in black & white…

    The Hall of Presidents only had eleven guys in it…

    Some of the features in Tommorowland included the television, and airplanes…

    (Okay, I’m done now.)

  • Hmmm. I just reloaded the code, and it seems to work fine for me. I would say check your wiring, and make sure that you’ve copied all of the code. If you’re still having trouble, you can always reach out to support@sparkfun.com. If you’re getting an error message in Arduino, let the support team know what that message is, that will help them to help you.

  • It’s more common to just say

    pukeSound++;
    

    Yes, thank you! As I was finishing up the code for this project at about 2:45am on the first day of my vacation, I knew there was a more succinct way to code it, but could not for the life of me remember it. I had considered randomizing, too, but again, at 2:45am, I was willing to let that go!
