Start with One Decision

Logic builds become easier when every gate answers one clear question. Begin with a simple condition, confirm the output, and only then connect it to the next stage.

Good First Projects

  • A door that can be opened from either side.
  • A safety interlock that stops a machine while a gate is open.
  • A sensor-controlled watering pass.
  • A status light that shows whether a mechanism is ready.
