Our shield is going to light up lights, and connect to sensors.įirst thing we need to do is make a new project. Since talking in the abstract all day is a pain the neck, we’re going to make a simple shield that does a few simple things. I told you I couldn’t help you with your shield idea. Once you have the Sparkfun.lbr, copy it into the “lbr” directory in the directory EAGLE is installed in. Another library I highly recommend (but is not necessary for this tutorial) is Adafruit Industry’s Eagle Library. This means you can use it commercially, so long as you share any adaptations your create. (Footprints are the measurements for parts that end up on your printed circuit board, and it is absolutely crucial that they’re correct.) One advantage of the SparkFun library is that everything in it licensed under the Creative Commons 3.0 Share-alike license. I like this library because it has a wide variety of components and reliable footprints. This is an Eagle Library made by SparkFun Electronics. You should get a file called “Sparkfun.lbr”. Here’s ours.Īfter you download and install EAGLE, download and extract the Sparkfun library. An EAGLE CAM job for separating out Gerber files.Your preferred Fab house’s Design Rules – Our PCB order rules are here.A copy of the SparkFun EAGLE library – for the components.A copy of CadSoft’s EAGLE program – for laying out your PCB.An idea for your shield – I can’t help you with this one.You’re gonna need these things before you get started. At this point, I’d be surprised to find someone who’s unfamiliar with computing, but has a strong enough interest in electronics to be to the point of designing their own PCB. I’m gonna go with some things that are EAGLE specific, but you need to know basics. This isn’t going to be a “how to use your mouse” tutorial. Okay, one more thing: I assume you know how to use your computer. It’ll just be easier this way, I promise. This is because I don’t want to try to teach you how to make parts on top of everything else we’re going to be doing. Lastly, for the sake of simplification, we’re going to make a board that uses only parts in the SparkFun Library. So come check out our PCB order, because it’s awesome. As a result, this tutorial doesn’t have any info on etching your own PCB, just on getting the Gerber files out. We try to fill up our panels so we can get one out every 2-4 weeks, and we recently had to switch production houses. Second, this tutorial came about as a way of trying to get more people into my local PCB order. EAGLE is a complex program, and it’s pretty awesome. First, I’m not going to teach you everything about EAGLE. There are a couple of things you should know going into this. So here I’m going to tell you everything you need to know to make a schematic and PCB layout, and get a beautiful shield that will plug into the top of your Arduino. Instead of a rats-nest of wires piled about and plugged into your prototyping breadboard, you can have a nice clean shield with labeled connections and a smaller footprint. Although you can just plug in wires, there’s something very appealing about making a shield. Who cares, You’re ready for the next step. You’ve made a robot that was pretty cool. You make blinking lights, and beeping noises. If not, I hope you find something useful here -Aaron) If you’re making a shield, have fun and good luck!. If you’re interested, I’ve started to sell the most recent version of my Arduino ProtoShield. I learned all of this stuff while working on my first PCB. (This tutorial has gotten really popular recently, and I’m very pleased that so many people are interested.
