Ordinary staples can be used for short wire links in breadboards, but they may corrode over time, especially in moist or corrosive environments. While staples are conductive enough for dry conditions, they are not ideal due to potential rusting and electrochemical reactions with the breadboard's metal. Solid stranded copper hookup wire is recommended as a better alternative, as it avoids corrosion issues and is easier to work with. The suitability of staples ultimately depends on the materials involved. Overall, using proper wiring is advisable for long-term reliability in breadboard applications.
