Concepts
A circuit needs a closed path from power to ground. Breadboards and jumper wires let you test that path without soldering.
A microcontroller reads inputs such as buttons or sensors and drives outputs such as LEDs, displays, motors, or signals through code.
Build path
How to use it
Start small, test the fit or circuit, then combine it with the rest of the project.
1
Build one small circuit first, then add parts one at a time.
2
Connect ground first, then power, then signal wires.
3
Upload a simple sketch and test the part before combining it with a larger build.
Connection guide
Wiring maps for the first test
Use the visual map before adding extra modules, displays, motors, or code.
3-pin sensor module wiring
Most 37-in-1 modules start with VCC, GND, and one signal pin. Wire ground first, then power, then signal.
