  • In the production of a variety of interactive work with Arduino, often use some common sensor or circuit module. For those who are familiar with the electronic circuit, the use of bread board or universal board to build a number of simple modules of the circuit is certainly possible, but for those who are not familiar with the circuit or a slightly complicated circuit, it seems not so suitable.

  • The use of this expansion boards can be easily connected with some commonly used analog sensors, such as light sensor. With the support of the expansion board and the corresponding circuit module, we only need to connect the corresponding sensor module with the Arduino connection, even if the circuit is complete. Since the specific details of the circuit are realized by the corresponding sensor module, because these we need to consider only how to write the corresponding program in the Arduino to read the data from these sensors will be able to.

  • The V4 version also uses a stack of design, which can be used in conjunction with the rest of the store. At the same time, it has also modified the linear order of the digital sensor interface, more convenient for the connection of various sensors, can directly connect the servo motor; -)
