octoliner-line

amperka/octoliner/octoliner-line

A quick-start node which represents Octoliner board tracking the line. The line tracking values lays in the range [-1,1]. The 0 value shows that line is at the center position relative to the sensors (between CH3 and CH4). The -1 value corresponds to the extreme left position (CH0) while the 1 to the extreme right (CH1). On boot node initialasizes the oprocoupler sensors and sets up their default brightness and sensitivity parameters. Possible errors: — Invalid I2C address
