Shield (Arduino)
makerAn extension board that enhances the capabilities of microcontrollers by providing additional interfaces and modules.
expanded
In the maker community, a shield is a circuit board that connects with a microcontroller, such as Arduino, to offer expanded functionality. Shields facilitate tasks like motor control, sensory data acquisition, or communication, by seamlessly stacking onto the microcontroller using a compatible pin configuration, thus allowing for modular and scalable project design.
examples
Arduino Motor Shield R3 allowing for control of motors using pulse-width modulation.
Utilized in robotics projects where motor direction and speed control is necessary, such as a small autonomous robot.
Arduino Ethernet Shield 2 providing network connectivity through an RJ45 connector.
Commonly used in IoT (Internet of Things) applications to enable microcontroller communication over LAN for data transmission or remote control.
