The Kitronik :MOVE Line Following sensor board adds line following sensors to a project. The 2 LED/phototransistor sensors output an analog voltage that can be read on the ADC channel of a microprocessor. Although designed for use with the Kitronik :MOVE Motor for BBC micro:bit, this board can be used with other boards, such as Arduino and Raspberry Pi Pico, as well as other micro:bit buggy/robot projects The board has the following connections: 4-pin connectors are in standard 0.1” (2.54mm) pitch. The pins provide connections for power (3V and 0V) and 2 sensor outputs, with L and R labeled for the left and right sensor respectively. The board requires a 3V – 5V connection (typically 3.3V) and a ground connection to the pin header. These pins are marked on the board as 3V and 0V The sensor output voltage changes from the supply voltage to 0V as the sensors pass over light and dark surfaces. Different surfaces will reflect different amounts. A typical bright surface will for example give a value of 0.5V. A typical dark surface will give a value of 2.5V (assuming VCC 3V). The value in a program will depend on the range and amplitude of the processor’s ADC Features: Add line following to your micro:bit Robot/buggy Can be connected directly to the underside of the :MOVE Motor No soldering required Although designed for use with the Kitronik :MOVE Motor for BBC micro:bit, this board can be used with other boards, such as Arduino and Raspberry Pi Pico, as well as other micro:bit buggy/robot projects
