12boards
Board Lab
From the Arduino Uno R3 to two FPGA boards: lessons, a live code editor, schematic and breadboard views, a serial monitor and failures that really trigger.

Learn hardware by building it
12 boards, 13 robotics benches and 13 drones, each a hand-inked 3D figure you can turn, wire, code and break on purpose.

The three labs
13benches
Robotics Lab
Motor drivers, sensors and power stages, built part by part on the bench, with practice tasks, quizzes after each step, live status and current draw.
13drones
Drone Lab
From a Tiny Whoop to an octocopter: a part-by-part build, live weight and thrust maths, safety tests, real Betaflight and ArduPilot settings, and a flying range.
In every lab
See through it
Drag to turn any figure all the way round, switch on See-through and watch the parts inside work, with labels that light up.
Run real code
Edit Arduino C++, MicroPython or Verilog and press Run: the simulator drives the figure, the pins and the serial monitor.
Break it on purpose
Reverse the polarity, brown out the supply, leave out a part or make a cold joint, and see what really goes wrong.
Arm and fly
Build a drone, check its numbers, run the smoke stopper and motor tests, then fly gates in angle or acro mode.
Nobody has to build alone
Shared rooms
Open a room on any board, robot or drone and send the link. Up to eight people share one bench, one at the keyboard.
A lab partner
Muse Spark finds you a build buddy whose skills fit yours, then plans a build night you'll all enjoy.
Six languages
