IR sensor tracking for Arduino for projects following on line.
How it works IR sensor tracking for Arduino :
The sensor continuously emits infrared rays ICL. If what is in front of an obstacle or an object, then the ICL are reflected from the surface of the object and the sensor, in turn, captures this reflected the ICL. Thus, the sensor detects that the predetermined zone is subject. If in a given subject area is not something sent by the ICL does not find reflection surface. Thus, the sensor detects that the predetermined zone is no object.
Note. Best action IR sensor tracking for Arduino occurs when contrasting shades of colors, perfect - black on white.
The output voltage signal IR sensor tracking for Arduino : TTL (if you see the black line - the low level signal, respectively, if he sees a white line - the high level of the signal). This allows the robot to follow the line or in the specified range.
An example of using IR sensor tracking for Arduino :
If the bright surface of arbitrary draw a black line, the use of these sensors mounted on the bottom of the platform will allow your robot to move strictly on your incised lines.
The sensor mounted on the door, when the door is closed will be reflected from it (thereby indicating that the door is closed). Once the door opens, and the size of the gap will increase by more than 2 cm, the sensor immediately fix it. At the same time, at your request, can activate the alarm system, or cheerful music, or maybe just light.
