Hatch · the Arduino editor built for classrooms
Students drag blocks. The board runs on screen first. When a real board reaches the desk, the same program goes onto it in one click.
Runs in Chrome or Edge with a school account. The desktop edition comes with the Composite Skill Lab programme.
Think Inside the Box - Try, Fail, Fix, Learn - Educators before equipment - Fit before ambition - Hardware is the reward - Creativity as a skill - Kept while it happens
What is in it
Blocks that write real code
The blocks carry real vocabulary: pinMode, delay, Serial.println. Scratch's wait 1 seconds and forever are not here, because a student who learns those has to unlearn them later.
One tab over, the C++ the blocks generate. A student reads it long before they write it, and on the day they start typing, nothing about it is unfamiliar.
pinMode(13, OUTPUT);delay(500);Serial.println("ready");
A board on screen
A class of thirty rarely has thirty boards. Hatch draws the board and runs the student's program on it. The LED lights, the buzzer sounds, the matrix draws a heart. Everyone works in the same lesson at the same time, whether or not a board reaches their desk that day.
When a board is there, the same program uploads to it in one click.
one board on the table, thirty in the lesson
Sensors that plug in
Arduino's Modulinos are small sensor and output boards that plug into the UNO with one cable: Buttons, Buzzer, Distance, Knob, Movement, Pixels and Thermo. Hatch draws each one you add and lets you drive it by hand. Slide the distance. Turn the knob. Press the button.
Each Modulino has its own blocks, so a student can write for a sensor the school has not bought yet, and know it works before it arrives.
A course that marks itself
Each track builds one named project over six lessons: the Rescue Beacon, the Fever Checker, the Smart Night Light. Every lesson has three tabs, Read, Think, Task, and a Check button.
Check runs the student's program and looks at what it actually did. Any working solution passes. There is no hidden right answer to guess at.
Progress follows the learner. A lesson finished on one laptop is finished on the next one they sign into.
30 tracks 180 lessons
Browser and desktop
From the Rescue Beacon to a weather station, and a project of your own.
18 tracks 188 lessons
Desktop edition
From the two cores and the bridge between them to TinyML, computer vision, on-device language models and ROS2.
AI Studio
A student trains a model on their own images, poses, hand gestures or faces, using the laptop's camera, in the browser. The model becomes a block, and the block drives the board.
Nothing leaves the laptop unless the student chooses to send it to the Arduino.
A dashboard you can share
Cloud Dash is a no-code dashboard for the values a board is reading and the things it can switch. A student drops in a switch or a gauge, points it at a block, and the dashboard goes live.
It shares by link and PIN, so a parent can watch the classroom's plant sensor from home without an account.
Examples
Nine finished projects open with one click, from a Beep Box to a Theremin. A student runs one, watches the board do it, then pulls it apart to see why. Every example works in the simulator.
For teachers
A teacher sees which boards in the room are online, opens a student's project read-only, and sends a suggested fix. The student chooses whether to apply it. Nothing is overwritten by an adult.
Accounts come from a roster the school uploads. Each student signs in with a username and a PIN, and their progress follows them from machine to machine, so a reset laptop no longer loses a term's work.
What does not exist yet: class reports, rankings, and a dashboard you could put on a wall. We would rather say so here than have you find out in the lab.

FAQ
Yes, with a school account, in Chrome or Edge. The browser edition runs the simulator, the full R4 course and AI Studio, and it uploads to an Arduino UNO R4 WiFi over the browser's own serial connection. Other browsers can run everything except the upload.
The browser edition is the school edition, and it is locked to the Arduino UNO R4 WiFi on purpose. One board, learned properly, beats five half-learned. The desktop edition adds the Arduino UNO Q and its Edge AI course.
The browser edition does, since compiling happens on our server. The desktop edition ships with the Arduino cores bundled, so the first compile works with no internet. Internet is needed for cloud features and updates.
From us, or from a roster the school uploads and we approve. There is no public sign-up, on purpose. A student signs in with a username and a PIN, and their lesson progress follows them to any machine.
Not as a product, and we would rather say so. Today a teacher sees which boards in the room are online, can open a student's project read-only, and can send a suggested fix that the student chooses whether to apply. Class reports are the next piece of work.
The desktop edition comes with the Composite Skill Lab programme. Browser accounts are priced per school with the programme they sit inside, so we quote on a call rather than publish a number we would have to qualify.
It is built on Scratch's editor, which is open source, and then changed substantially for hardware. It is not made by or endorsed by the Scratch Foundation or MIT.
