Through patrol technology, we can control robots or vehicles to move along artificially designed lines automatically. This technology is widely used in the automation industry, such as material turnover of production line, goods transportation of logistics warehouse, and also simple unmanned driving can be based on patrol technology. ↓

Line Finder Card uses infrared sensors to find its way around. By laying white lines on dark ground, several infrared sensors can clearly detect the movement and feed back signals, allowing the robot or car to adjust its direction in real time.

Line Finder Card features MV358 comparator, and it is ideal for building a line following robots. On the back of the Line Finder Card, there are three sets of sensors consists of IR emitting LED and an IR sensitive phototransistor. Each sensor is capable of detecting a black line on the white background or a white line on the black background.


Spec:

  • • Digital output mode: TTL (High when black is detected, Low when white is detected)
  • • Integrated three LED indicators
  • • Adjustable detecting range
  • • Power supply: 5V DC
  • • Comparator: LMV358
  • • Photo reflective diode: RS-06WD
  • • Connection: Goldfinger / Cable
  • • Dimension: 40.5 x 33 mm

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.
