Your wiring starts here
Loading the first sample…Static wiring, not a circuit simulator. Supported samples use an Uno R3 and a fixed 300-hole breadboard. Component fit and real hardware behavior still need checking.
A little syntax goes a long way Quick reference + current limits
Describe connections only
Begin with bread 0.1, declare a part with part led: led-5mm-red, then connect its pins with led.K -- uno.GND. Use // for comments.
A deliberately small playground
Try one or three to six resistor/LED branches, or the mixed-parts wiring study. Arbitrary circuits and manual layout are not supported. Six-LED and mixed diagrams can have crossing wires; a crossing is not a junction.
