hi everyone. I have this problem. i need to interface an infrared receiver with the computer so that when the signal is disrupted, this information will be passed immediately to the computer which will in turn make a camera connected to it capture an image automatically. for like when a person passes in front of the sensor. but i want the sensor to sense very small object. the images are then procesed in the computer which i can do. so if anybody can help with ideas please. i'm fluent in C++.
