If we use closed hardware design, we need to design and manufacture complex circuit boards, which is time-consuming and laborious. On the contrary, on the open source hardware, in order to let people use, copy, research and change freely and openly, it has designed many open interfaces to meet the development needs of different users. Take Arduino Duemilanove developed by Arduino in 2009 as an example. It is equipped with 1 9V DC inputs, 1 USB interfaces, 1 digital input/output ports, 6 analog input/output ports, 1 5V DC outputs and 1 3.3V DC output ports. Rich ports provide convenience for design, and students can use these ports to design various works, even if the ports are insufficient.
2. Have various interactive components.
Sensors are only one kind of interactive components, and can also be controllers, sensors, functional modules, motors, relays, power supplies and other types, and each type can be subdivided into many different categories. Rich interactive components make it easier and easier for students to design works when designing maker works.
3. This is an open and shared culture.
Through the maker design of open source hardware, students can directly participate in the open source culture brought by open source hardware. On the Internet, you can easily find an open source community composed of open source hardware enthusiasts, where students can share their works and exchange creative experience.
