Prototype Shield with Breadboard – Arduino Compatible USB rfid and zinc chlorideIntroduction : The Arduino UNO Prototyping Shield is designed to facilitate the development of custom circuits directly atop the Arduino UNO board. It offers a comprehensive prototyping area suitable for both through hole and surface mount components, including a 14 pin SMD footprint. Integrated features such as power lines (5V and GND), a solderless breadboard, and convenient access to all 14 Arduino I O pins streamline the prototyping process. This
