Infrared is an electromagnetic wave with longer wavelengths than red visible light. In addition to its important applications in medicine, it is widely used for close signal transmission because of the advantages of low device cost, simple technology and good confidentiality. The most common example is an infrared remote control.
Infrared transmission system needs emitter and receiver to work together. IR Receiver Card is a receiver, which can receive infrared signals from various sources, read data instructions, and realize wireless communication, to build the project in a simple and quick manner.
IR Receiver Card allows you to detect infrared (E.g., IR signal from a remote controller). There is an IR detector on the IR Receiver card which is used to get the infrared light emitted by the Infrared Emitter. It can detect a modulated IR signal at 38 KHz. The distance between the IR Receiver card and the IR source should be less than 10 meters.
Longan Cards is a unique open source development platform designed by Longan Labs. As a plug and play development platform, Longan Cards allows you to quicky build wide array of prototypes and applications in no time. A full set of Arduino libraries and plenty of example codes are available to play with Longan Cards platform.
NOTE: IR Receiver Card supports two wire I2C bus interface.

↑ Longan Cards system consists of Cards and Boards. There are many gold finger antennas on Card and several gold finger sockets on Board. They are combined together through sockets interpolation, which is intuitive and easy to use. With this unified and flexible interface, you can realize a variety of ideas. Many more Boards with different themes would luanch to help people explore more fun.
↑ Longan Cards modules are classified into many types. Firstly, the main control cards which are the heart of Cards system, run the code and take charge of the exchange of data between modules. Besides Carduino, you can also use MicroBit, Arduino and other development board through connection board. The sensor cards can detect data of surrounding such as temperature and air pressure, etc. The inputs cards allows you to do some operations, such as buttons, knobs, etc. The output cards give feedback in various forms, such as buzzers, motor drives, etc. The communication cards can transmit data in many ways, such as Bluetooth and 4G network. The power cards supply power for electronic projects, including batteries, DC, etc. And other cards, mainly do some auxiliary work, such as expansion, code downloading, etc.
↑ STEM is an acronym for science, technology, engineering, and math. STEM education began in the United States in the 1990s. It is an interdisciplinary teaching method that combines STEM content and real life situations, which helps stimulate students’ original curiosity and thirst for knowledge and novelty. Longan Cards contains dozens of modules, involving a wide range of knowledge in the process of use, including electronic circuit, mechanical structurenature, programming, science of nature, daily wisdom, and humanities, etc. It is a powerful tool for STEM education at fields of electronic prototyping, science experimentation and DIY project.
