Arduino is an open-source platform that includes both hardware and software. The hardware of Arduino contains many programmable circuit boards as a microcontroller for connecting sensors or other modules to build up a project. The software of Arduino is Arduino IDE, it is an easy-to-use programmable platform with plenty of libraries and API for software development. As it is an open-source platform, there are many contributors sharing their ideas in the forum. A mass of open source codes can be found as well for learning and further discussion. In terms of Arduino products, we provide many Arduino boards such as Arduino Uno, Arduino Mega, etc. Besides, there are also many extend boards based on the Arduino platform such as Seeeduino Boards. In order to be compatible with our Grove system, we have released many shields for Arduino or Seeeduino which includes Grove interface to connect the boards and Grove modules easily without jump wires. For different users, we also provide kits for different needs. You may need some accessories like wires or cases as well, you can find them in our Accessories catalog.
