Amperka Octoliner reflectance line Sensor Array for Arduino and Raspberry Pi line Following Robots / 8 Channels I2C 35 Volts onBoard Processor

If you're building a line following robot Octoliner can be the eyes of the robot. No matter whether you control the robot using Arduino or Raspberry Pi, Octoliner will fit any project. "Octo" means eight: Octoliner combines eight TCRT5000 sensors into a line sensor array with a dedicated processor on a single board. The processor converts analog signals from all sensors, preprocesses it, and then provides ready-to-use data to your mainboard via the I2C bus. This architecture makes the sensor compatible with virtually any development board. Only two signal wires with 3 to 5 volts level are required to talk to the sensor. You are free to choose analog or digital mode. That is, you can consider each channel as a binary black/white sensor, or you can read shades of gray to track line edges more precisely. Furthermore, you can set up the sensitivity level in software to dynamically react to ambient light changes. The Octoliner PCB has a few mounting holes for M3 (1/8") screws spaced in multiples of 10mm (~3/8") to fasten the sensor to a chassis. To wire the sensor, use the 3? standard 2.54mm (0.1") spaced male pin header. Only four pins need to be connected, actually: Voltage, Ground, SDA, and SCL. Use any four female-ended wires (not included) to connect Octoliner to your board. The Octoliner comes packed into a carton box with a booklet, which includes basic examples of interfacing from Arduino and Raspberry Pi, as well as GitHub links where you can find the libraries, more examples, and full documentation.
