Getting Started: Essential Tools and Components

This beginner's area is for anyone starting out in electronics. Learn what tools and parts you will need for starting electronics. A good place to start is to read the Start Electronics Now!

Basic Electronic Components

To begin your electronics journey, it's crucial to understand the fundamental components you'll be working with. Here's a rundown of some essentials:

Resistors: A resistor doesn’t “do” anything actively.
Capacitors: Capacitors are like tiny batteries.
Diodes: We saw previously in our Diode Clamping Circuit tutorial that a diode clamper is basically a wave. A Diode Clamping Circuit is an electronic circuit configuration which can be used to change the DC voltage level of an input waveform. Unlike diode clipper circuits, or voltage limiter circuits, a clamping circuit does not change the…
Transistors: With a transistor, you can amplify your signal, invert your signal, or lots of other stuff. Building logic gates using transistors is extremely easy to understand and a great way for the electronics beginner to learn more about logical switching functions. There are, of course, many different ways we can create individual logic gate…
Photodiodes: The Photodiode uses a pn-semiconductor junction to convert surrounding light energy into an electrical signal which can then be processed and used to monitor some physical condition. As such, photodiodes are a fundamental component in the branch of electron…
Phototransistors: The Phototransistor is another light-sensitive optoelectronic semiconductor device that conducts current when exposed to light. The phototransistor functions just like a standard bipolar transistor, but instead of using a base current, it uses incident l…
Thermistors: Negative Temperature Coefficient, or NTC for short, plays an important role in determining the thermal behaviour of various electrical and electronic components. There are multiple types…

Essential Tools

Multimeter: A multimeter is a measuring instrument that anyone involved in electronics will need to use at some stage.
Soldering Iron and Solder: Basic soldering for beginners in electronics.
Breadboard: The first step to getting started building circuits is to get a breadboard and just build lots of circuits on it for practice. The introduction to electronics is followed by twenty tutorials that use an electronic breadboard to build various circuits.
Stripboard: This video and article show how to build a circuit on stripboard.

Foundational Concepts

Understanding Current and Voltage

Yes, basic electronics is easy. An electrical current is the flow of electrons in a wire. Electrons flow when you have a “closed loop” - a path from the negative to the positive terminal of a battery. Many think that basic electronics has to do with the physics of how electrons move. The biggest misunderstanding about electric current is that current can be “used up”. Current is never “used up”! Check out our article What Is Electric Current? to learn more.

As for voltage, it’s important to know that voltage is always measured between two points. The second point about voltage is that the applied voltage to a circuit is always the same as the sum of the voltage drops. If you know this about current and voltage, then you know the basics.

Schematic Diagrams

To make any electronic circuit, you start with a schematic diagram. A schematic is a drawing of a circuit. The lines between the components tell where you need to make connections to build this circuit. To build a circuit from a schematic, you have to create the same connections that are on the schematic in real life. From the schematics, you can also design a printed circuit board if you want. When your circuit board is created, you solder your components onto the board. Voila! Knowing how to read and design schematic diagrams.

Learning Resources

Our tutorials explain, teach, and inspire electronics enthusiasts and beginners alike. We have a wide range of tutorials covering both basic electronics theory and project build examples. The tutorials are written by the experts, and they are filled with high-quality images to help you through.

Our tutorials are all sorted into a series of categories: concepts, technologies, skills, hook-up guides, and projects.

Concept Tutorials: Our concept tutorials cover the really low-level, nitty-gritty areas of electronics.
Technology Tutorials: Technology tutorials speak specifically about the components, standards, and technologies which make all of this possible. You can learn how GPS works and how you might add it to your project.
Skill-Based Tutorials: Electronics isn’t just about calculating currents, voltages, and resistances. You have to learn some (sweet) skills to build the stuff!
Hook-Up Guides: Are you looking for a quick primer on using a new Arduino shield or breakout board? This is what our hook-up guides are geared towards. These tutorials will usually include an explanation of a specific product as well as example schematics and code to get it quickly up and running.
Project Tutorials: If you’re seeking inspiration for projects of your own, check out some of the stuff we’ve done. These tutorials are detailed enough that you can follow along and build an exact replica. Or you can riff on our project, improve it, and make it your own.
Articles: If we write a tutorial that just doesn’t fit any of the above categories, we’ll stick it in the articles section. Here you’ll find stuff like how to navigate FCC requirements or how we assemble our products. These are good reads and contain important information for someone out there…

Hands-On Learning: Kits and Projects

On our online retail store, we sell anything from beginner’s soldering kits to advanced development platforms. What better way to start learning than by doing? Our kits help explain basic electronics concepts, while also allowing you build something fun and functional. Find our recommended beginner kits in the Starter Kits section of this guide and start building!

Starter Kits

We want to get everyone out there as geeked out on electronics as we are. If you’re looking to avoid the soldering iron for now, check out the SparkFun Inventor’s Kit. This is a beginner’s electronics kit, which features an Arduino microcontroller. You'll quickly be blinking LEDs, spinning motors, and scrolling messages on LCDs. For more starter kits, check out the kits category on our store!

Wearable Electronics

Electronics doesn’t always have to mean soldering, wiring, and breadboarding. We’re also really into wearable electronics (e-textiles), an amazing melding of both sewing and electronics. Using conductive thread we can sew battery packs, LEDs, and microcontrollers into fabric to light up backpacks, dresses, jackets, or whatever. With the ProtoSnap LilyPad Development Board, you’ll be introduced to sewable electronics through the LilyPad system, a technology developed through a partnership between SparkFun and MIT Professor Leah Buechley.

Educational Classes and Workshops

Our passion for teaching electronics extends beyond the computer screen. Visit our Classes page for information on upcoming events. We teach anything from squishy circuits (learning electronics with conductive play-doh) to how to design a circuit board. In the summer of 2013, we’ll be embarking on a national tour, spreading our electronics gospel throughout the country. Go from blinking an LED to virtual prototyping in seven hours and still have time to eat lunch!

This class is for anyone who has never played around with Arduino before and those who have played around a little bit but aren’t entirely sure about how the basics work. It’s easier than you think! We will put together basic single component electrical circuits, learn about analog and digital, input and output, basic programming concepts, practice very basic Serial communication, and briefly cover basic virtual prototyping.

Combining Scratch -- a freeware, drag-and-drop, block-programming environment -- and the PicoBoard, students as young as five can learn how to integrate sensors into projects. They will learn things like how to use a light sensor to control the background of their animation, use a slider to control the speed of their character, and how to create their own sensors.
