Circuit Playground Bike Light – AGM Summer Break | DigiKey


(lively music) – Hi, my name is Grace. And this is Digi-Key’s
Another Geek Moment, summer break addition. Thanks to our friends at
Nordeast Makers in Minneapolis for letting us use their
makers space for our projects. Today I’d like to talk to you about my circuit playground bike light tutorial found on maker.io. There’s simple components in this, as you can see there’s only these three. And I’ll start with
the circuit playground. This is the main component of the design. It is very inclusive. It has a lot of different
sensors on here that you can use. It has microphone, accelerometer, some capacitive touch, and lots of other things you
can tie into your design. For my design I was making
the bike light powered by this switch, and then
this lithium battery. So I started by learning
more about the neopixels, as that’s what I would use for my display. This webpage, the circuit
playground bike light, offers a very in depth explanation of how you can code the RGB color codes or the hexadecimal numbering system. So I used hexadecimal. Pretty much just calls
out what percentage of red light you’d like, what percentage of green and
then what percentage of blue. You’re going to have
to begin by downloading the Arduino IDE from arduino.cc. So, I’ll begin talking you
through the code of it. (lively music) Now you can begin uploading
some of these sample codes from the project page that
I mentioned previously. We will take this spinner,
I believe it’s called. Once you have your code uploaded, you can plug in the switch
in the lithium battery so that it can run without your computer. You’ll be able to attach it to your bike. And at this point you should be able to turn it on and have your code. Now you can go ahead and
attach it to your bike. I’m just going to use
some simple zip ties, but if you’re going to
use it in different types of weather you might want to
have something more robust, so your circuitry doesn’t get ruined. You will see that this color display looks a lot like spring, and that is intentional. In this specific temperature range, it should be showing your pinks and your greens and your yellows. With the bright yellow light, because it is on a bike,
and you do want to be safe. So yeah, there’s lots of
codes offered on the webpage. Simpler things that you can
use as reference as I did. With this application and my bike light, those were very helpful, they had flashers and spinners and all different names for codes. But moving forward, there’s
lots of different sensors I could have tied into this project, that I decided not to. If you’re interested in exploring that and trying this project, there are about 50 projects
or more on maker.io. And if you’re unfamiliar with that, that is Digi-Key’s maker page. It will help walk you
through some different ways you can take this circuit playground. You can get this board for
20 dollars from Digi-Key, and for all it offers,
it’ll give a novice like me a perfect opportunity
to learn Arduino’s IDE or just programming in general. And it did just that. I’m not done exploring with this. There’s five or more very
useful sensors on here and different capabilities, that I would be very interested in tying to something maybe
larger than a bike light. I could see using this in my biomedical classes or applications. Maybe you put this on your patient’s leg, and the accelerometer will blink if they are moving too
fast if their elderly, or you know, a number of things. But, yeah. Now let’s go enjoy our project. So now let’s go and ride bikes safe. Let’s go practice some more programming. (lively music) Now let’s go ride our bike
around fabulous Minneapolis. (lively music) If you haven’t checked out
Noah’s skateboard video on maker.io, please do. Alright, let’s ride. – Alright, let’s get to it. Thanks for watching. (lively music)
