Proto-shields are boards designed to expand the capability of embedded projects using popular platforms like Arduino for prototyping. As an expansion board, or daughter card, they provide a platform for the user to integrate his/her own functionality and components, above and beyond the standard functionality of the platform.

A proto-shield does this by surrounding and covering the existing hardware of the chosen platform. This allows for the addition of peripherals or pre-manufactured boards with specific functionality. It also gives the user the opportunity to customise a project by adding either soldered components or ICs.

Proto-shields have become increasingly popular because of the flexibility and cost advantages that they provide. They can be used to bridge the gap between a relatively inexpensive platform and complicated hardware requirements, allowing users to bring their projects to life cheaply and quickly.

In addition to the advantages of cost and flexibility, proto-shields also offer a degree of protection for the electronics inside. Depending on the complexity of the project, it may be possible to avoid the use of casing or protective containers. As a result, projects become more durable and can withstand the rough environments sometimes encountered in industrial applications.

The working principle of proto-shields is a simple one. They are designed as the link between an embedded system and the various hardware components that may be required. The board gives the user the ability to integrate a wide range of extra components, including solderable parts, at a relatively low cost.

For Arduino projects, a standard I/O connector is provided on the board, allowing for the connection of a wide range of extra peripherals. A resistive network is also included to protect the board from current overloading. Optional components, such as LCDs, LEDs and audio devices can be integrated for enhanced functionality.

The use of proto-shields also allows for the integration of more advanced functionality. Users can add components such as buzzers, RF receivers and wireless communications modules to create more complex projects. This gives the user the ability to create products that can interact with each other, enabling projects to run autonomously.

Overall, the proto-shield provides an excellent platform for prototyping and electronics development. They are cost-effective and easy to use, and allow for the fast integration of extra components. In addition, they are robust and can withstand harsh conditions, making them particularly useful for industrial applications.
