From Arduino prototype to industrial installation

The 15-point checklist, free. What separates a bench prototype that works from a control cabinet that lasts years on the plant floor.

• The 15 verifiable points — power, wiring, protection, communications and mounting, each with its concrete check.
• The typical mistakes to avoid — the failures that kill a prototype in production, caught before they cost you a shutdown.
• The printable workshop checklist — take it to the cabinet and tick it off point by point.
