Core
Meet the eBrain.
Identify the controller, power connection, programmable connections, and the safe starting state before anything else is attached.
Hardware foundations
Build the system.
Start with a reliable eBrain, add one part at a time, test it, and turn working modules into a reusable invention toolkit.
Connections
Add one input or output.
Build in small modules. Connect a single component, check its wiring, test it, and label what worked before adding the next system.
Validation
Test before you program.
Use the app library to confirm that the eBrain can read the input or control the output. A known-good module makes coding much easier.
Expansion
Combine working modules.
Bring together sensing, light, sound, motion, controls, and structure only after each piece works on its own.
