Light is ubiquitous in the world around us. The sun, a lamp, a monitor, a candle are all objects that give off light. Objects that do not emit light are seen by reflecting light into the human eyes. The oldest example is the moon. ↓

Light Sensor Card measures the intensity, or brightness, of the Light. This is done with photoresistors. When light intensity increases, the resistance value of photoresistor decreases, while the resistance value increases when light intensity decreases. Through this rule, we can transform the change of light intensity into the signal of the circuit for further analysis and control. ↓

Many environmental information can be obtained by detecting the change of light intensity, such as the time range of day or night, and whether the lamp is turned on or not inside house. Light is also a simple wireless control signal. We can control a mechanical car by the light of the torch.

Light Sensor Card features TEMT6000 ambient light sensor. It is sensitive to the visible spectrum. With Light Sensor Card, you can bring the ability to detect light level to any projectIt outputs values ranging from 0 - 1023 where 0 indicates dark and 1023 indicates bright light. If you want to get the visible light intensity in lux (lx), check out our other version here.

Longan Cards:

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.

↑ 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.
