Library to work with the "Octoliner" breakout board by Amperka. "Octoliner" represents 8-channeled infrared line sensor based on TCRT5000 optocouplers and the GPIO ports expander controlled throuht the I2C bus.
Nodes to work with WS2812 (NeoPixel). The main difference from the other libraries that this library does not use a buffer to light up the LEDs. So it gives a possibility to light up a really long LED strip with a small microcontroller without a huge amount of RAM.
