Snap Circuits: 4 Award-Winning Electronic Kits

Electronics permeate our lives, from the televisions in our living rooms to the smartphones in our pockets to the everyday devices—light switches, fans, digital clocks, you name it—that make our world more efficient and convenient. Yet for many, the inner workings of these electrical devices remain a mystery.

Enter Snap Circuits, Elenco’s innovative electronics kits that illuminate the world of electronics, teaching everyone from ages 8 to 108 about circuitry in fun and engaging ways. Snap Circuits employs one-of-a-kind snapping components and colorful beginner-friendly instructions that make learning electronics fun, safe, and approachable. 

The award-winning kits are taking STEM education by storm, making their way into classrooms and homes, and providing hours of playful building and prototyping. Here’s everything you need to know about this groundbreaking electronics kit.

What are Snap Circuits?

Created by Elenco, Snap Circuits are a popular line of educational electronic kits that are designed to teach basic engineering, electronics, and circuitry principles. 

The kits contain innovative snap-together electronic components and a colorful, user-friendly manual with numerous project ideas. The patented safety devices and snap-together design make it convenient to experiment with different circuit configurations and learn about electricity in a safe, beginner-friendly way. 

Here are some of the key features that make Snap Circuits stand out: 

Innovative Electronic Components that Snap Together

Snap Circuit components

The plug-and-play kits consist of electronic components in the form of plastic modules that snap together to create electrical connections on a circuit board device.

The snapping modules include resistors, capacitors, transistors, LEDs, switches, motors, and other common electronic components. The components are large, colorful, and numbered so they’re easier to identify and much harder to lose when compared to traditional components. 

Beginner-Friendly Manuals with 100+ Project Ideas

Snap Circuits Manuals

All Snap Circuits kits come with a project manual containing step-by-step instructions and color-coded, labeled diagrams for building a variety of circuits, such as alarms, radios, doorbells, light switches, and more. 

Each project is accompanied by a clear explanation of the underlying principles and concepts, helping users understand the fundamentals of electronics.

Patented Safety Features 

Snap Circuits safety kits

Snap Circuits uses Elenco’s Circuit Safe Fuse Technology, which provides an added layer of protection against excessive current flow and potential damage to the circuit or components. These and other safety features make it possible for young children to explore electronics in a way they never have before. 


Snap Circuits awards

Snap Circuits’ one-of-a-kind approach to electronics education has earned them a variety of awards and acclaim, including Toy of the Year (TOTY), ASTRA'S Best Toys for Kids, Parent's Choice Recommended, Good Housekeeping's Best Toy, Family Choice, National Parenting Publications Awards (NAPPA Gold), Children's Choice, Dr. Toy (100 Best Children's Products, 10 best Educational Products, Green Toy Company), the inaugural Seriously STEM award, and the KAPi Award.

Best Snap Circuits Kits (+ Manuals!)

1. Snap Circuits® Jr. 100-In-1 Electronics Kit - SC-100

SC100 Snap Circuits Jr.

For example, one circuit, which teaches “how capacitors in parallel change the frequency of an oscillator”, has the project name “Electronic Cicada” and shows users how to build a circuit that creates the sound of the Cicada insect. 

This unique, playful approach to teaching complicated circuits makes this kit accessible to those with little to no knowledge of electronics. After completing just half of the projects, users will become familiar enough with circuitry and electronic principles to start generating their own circuits. 

4. Snap Circuits® Arcade Electronics Kit - SCA-200
