Build your own chasing LED light display...

And unlock the secrets behind circuits, timing, and visual effects!

A STEM kit that's sure to delight the kids—a great activity for parent-child bonding time! The Chasing LED Electronics Kit is a hands-on STEM project that lets you build a dazzling light pattern using real electronic components. With 81 red LEDs lighting up in a "chasing" sequence (which can be controlled using knobs and buttons), this kit teaches timing circuits, component placement, and analog control in a fun and rewarding way.

Ideal for ages 12 and up, this soldering kit is a perfect gift for teens and adults alike who want to create something eye-catching and educational. With 81 LEDs and a large variety of other electronic components, this kit delivers hours of rewarding soldering fun! Once built, the LED display makes a great desktop gadget, gift, or showcase piece. Learn, solder, and light it up—literally.

Learning Outcomes and Benefits

Fundamentals of Circuitry: Understand voltage, current, resistance, and the flow of electricity as you connect and power your circuit.

Integrated Circuits in Action: Learn how the NE555 timer and CD4017 decade counter work together to create timed sequences—a foundational skill in digital electronics.

LED Sequencing & Visual Patterns: Explore how LEDs can be arranged and powered in patterns to create dynamic, chasing effects. Learn about serial vs parallel configurations and controlling LED timing.

Soldering Techniques: Practice precise soldering with through-hole components and integrated circuits, improving your hands-on electronics skills.

Analog Component Use: Use potentiometers and buttons to control animation speed and see how analog input modifies digital output in real time.

Power & Voltage Awareness: Understand how resistors and capacitors regulate voltage and protect sensitive components like LEDs from burning out.

Problem Solving & Troubleshooting: Build confidence by identifying and fixing issues—ideal for developing diagnostic thinking useful in all areas of STEM.

Frequently Asked Questions (FAQ)

Q: What does the finished kit do?
A: The kit creates a "chasing" light effect. LEDs light up in a moving sequence, creating an eye-catching animation you can control via the knobs and buttons. Kids will love creating interesting patterns with this kit.

Q: Is it beginner-friendly?
A: Yes, anyone can build this kit by following our illustrated step-by-step instruction manual. Younger learners (under 12) may need adult help during assembly—which provides a great opportunity for parent-child bonding time!

Q: Can I change the speed of the LED effect?
A: Yes! The included potentiometers let you fine-tune the speed of the LED animation in the horizontal and vertical (and in combination, diagonal) directions. Buttons also enable you to activate and deactivate different sections of the circuit to vary the effects.

Q: Does it come with a power source?
A: It includes a USB to 3.5 mm cable which can be plugged into any powered USB port (such as a phone charger, powerbank, or PC/laptop USB port).

Q: Is this a good educational gift?
A: Absolutely—it's ideal for anyone of any age who's interested in electronics, circuit design, or flashy visual projects. Great for teens, hobbyists, and even adult learners.

Usps

My kit order was shipped with the USPS,they messed it up and customer service went above and beyond with communication and follow up. Not only did they ship a replacement they also included another kit no charge even though they were not the source of the problem. The original kit was received by me days later and I was told I could keep it. The product is great and the customer service is excellent!

Hi Rick, thanks so much for taking the time to leave this review and for sharing your positive experience. We're glad you got your items in the end and that you enjoyed the free gift we sent you too. We've also bottomed out on the issue with USPS; there were two mailing labels on your pack (as the parcel was handed off to them by another shipping company) and they inadvertently scanned the incorrect label, causing the package to be routed for investigation for counterfeit mailing labels. After we provided them with the evidence that the postage was paid in full they then scanned the correct label and then released the package with their apologies.

LED Chaser - Nice kit for working with your child or grandchild.

Nicely made PCB and the design is wonderful for teaching the wonders of 555 timers and 4000 series ICs. I contacted support to obtain the schematic and they immediately sent me a copy so I can properly teach the theory of this circuit to my grandson. Super nice people at the science hut!!

Thank you so much for taking the time to leave us your review, we really appreciate it! We're always just a message away if there's anything else we can help you with. Enjoy building the kit with your grandson :)

Electronics kit for my daughter

My husband is an electronics engineer and our kids are fascinated by what he does. So I got this electronics kit for our daughter and another one for our son... they are using some of his tools to assemble them and having a lot of fun! Thanks

Great soldering practise

Very happy with this. Lots of components, so I was half expecting some of them to be blown or faulty but everything works perfectly. Nice little interactive gadget when it's assembled. While there are lots of components, this electronics kit is easy enough to assemble. A little case or housing would be a nice addition.

Soldering practise

Got this to practise soldering as I want to learn to repair and restore older electronic devices like radios and TVs... it served it's purpose well, lots of soldering practise with all the components that are crammed onto this circuit board. Good few more kits of various difficulty levels available here, I ordered the 6-bit clock today, looking forward to receiving it.
