Brief Introduction

When making various interactive works with Arduino, commonly used sensors or circuit modules are often used. For those familiar with electronic circuits, it is certainly possible to build some simple module circuits with breadboards or universal boards, but it seems less suitable for those who are not familiar with circuits or slightly complex circuits.

This expansion board can be easily connected to some commonly used analog sensors, such as light sensors. With the support of this expansion board and corresponding circuit modules, we only need to use dedicated connection wires to connect the corresponding sensor modules to Arduino, and the circuit part is completed. Since the specific circuit details are implemented by the corresponding sensor modules, all we need to consider is how to write the corresponding program in Arduino to read the data transmitted by these sensors.

The V4 version also adopts a stackable design, which can be used in conjunction with other expansion boards in our store. At the same time, the line sequence of the digital sensor interface has been modified to facilitate the connection of various sensors and enable direct connection to servo motors.
