Grove - Line Finder to Build Arduino Line Follower Robot

Description Grove - Line finder help you design line-following robotic projects easily and quickly. Those eye-like sensors on the board are actually IR emitting LED and sensitive phototransistor. When the phototransistor detects the reflected infrared light from the IR emitting LED, it will output a digital signal, which changes from HIGH to LOW. A line-following robot can sense a black line by IR emitting LED and sensitive phototransistor, then they will send the signal to microcontrollers. Finally, your robot will drive the motor according to the output of the sensors. Feature Grove compatible interface Small size 5V DC power supply Indicator LED Digital output Distance adjustable What is Grove? Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Not only are these open hardware, but we also have open-source software.
