Arduino Shields

Arduino Shields
They offer an easy and low-cost approach to add specific functionality to an Arduino. Arduino shields are boards that can be plugged on top of an Arduino board to increase its capabilities. This means that if you have a project you would want to make that involves a motor or something that would require you to do a lot of wiring and connections, there is a high chance that there is a shield that can make that in a much simpler and user-friendlier way. Instead of wiring, and having a lot of different components you can just plug the shield in the top of the Arduino board and that is it.

We need peripherals or accessories to use the Arduino Shields in a project. Displays, sensors, memory, and communication devices are peripherals. For instance, a 16×2 character LCD requires roughly 16 wires between the Arduino and the LCD. Beginners may struggle with this, but experts can accomplish it easily. However, a user who wants to use a 16×2 character LCD and a 4×4 keypad can double the Arduino-device cables. They make adding Arduino functionality simple and affordable. Arduino shields can be added to Arduino boards to boost their capabilities. Thus, if you want to construct a motor-related project or one that requires a lot of wiring and connections, a shield may make it easier and more user-friendly. You may plug the shield into the Arduino board’s top without wiring or many components.
