Sparky Lab
The coding lab: colourful blocks, a board simulator and a USB connection. In advanced mode you can see what the program does inside, one instruction at a time.
Coming soon · Sparky Kits and Sparky Lab
Build. Code. Invent.
Sparky is almost here: solder-free electronics kits and a coding lab in your browser. Build with your hands, code with blocks and watch your project come to life.

A first look
What Sparky will look like
-
Illustrative image (AI)
Sparky Design concept for Sparky, an interactive learning platform.
The illustrative images were created with artificial intelligence and show a possible look: the final product may differ.
What is Sparky
Learn electronics and programming by building things that really work
Kits
From the Alarm Kit to the Robotic Arm: the parts, a step-by-step assembly guide and the Lab ready for your kit.
Games
Challenges where your program controls what happens on screen. You press a real button, the program decides and Sparky jumps.
Community
A place to show what you have built, discover other makers' projects and try them in your own Lab.
How it works
From block to board, no hidden magic
The blocks are not a separate toy: they are the gateway to how a computer really runs programs.
-
Build
Plug the components into ports A–H: no soldering, no loose wires.
-
Code
Snap blocks together: "when the button is pressed", "turn on the light", "wait".
-
Simulate
Try everything in the simulator, in your browser, before connecting the board.
-
Bring it to life
Send it to the board: the light turns on, the servo turns, the alarm goes off. The same program.
The hardware
The Sparky Computer is the brain of every project
An ESP32 board with 8 ports labelled A to H. Sparky components (buttons, lights, light sensors, potentiometers, servos and a buzzer) simply plug in, with no soldering or loose wires.
Connect it to your computer with a USB cable, or play with it from your phone over Bluetooth.
No soldering
Block-based coding
Simulator included
Who it is for
Made for children, teenagers and curious minds of any age
Ages 8–12
First steps with colourful blocks, a guided tutorial, ready-made examples and games that work from the very first session.
Ages 13–17
Projects with real kits, pseudocode and an advanced mode that shows the virtual machine inside: the bridge to "real" programming.
Schools and teachers
Complete kits with assembly guides, a simulator for those who do not have a board yet and projects that fit in a single lesson.

When can I start using Sparky?
We are putting on the finishing touches. Leave your email and we will let you know as soon as the Sparky Lab and the kits are available. In the meantime, you can already try Sparky Explore.
Will I need a board to get started?
No. The Sparky Lab has a simulator in the browser. The board and kits are for when you want to take your program into the real world.
How old do I need to be?
Sparky is designed for ages 8 and up, with blocks and a guided tutorial. Older kids (and adults) have the advanced mode and the more complex kits, such as the Robotic Arm.
Will I need to install anything?
No. Everything works in the browser. To connect the board over USB, all you need is Google Chrome or Microsoft Edge on your computer.
Want to be among the first to try it? Or bring Sparky to your school?
Leave your email and we will let you know at launch. For anything else, write to us at equipa@sparky.pt.
