Enter the . This expansion board (or "shield") is designed to solve exactly this problem. It turns your messy breadboard into a clean, plug-and-play hub for sensors and servos.
You are prototyping a robot, building a weather station, or teaching a class. Do not use it if: You are building the final, compact product, or you need high-current motor control. arduino sensor shield v5 0 manual

If you are diving into the world of Arduino robotics or environmental sensing, you have likely encountered a frustrating problem: managing wires . Connecting a single LED or a button is easy. Connecting 10 sensors—a ultrasonic distance sensor, a servo motor, a temperature sensor, and an LCD display—results in a nest of jumper wires that looks like a bowl of tangled spaghetti.
