I'm a newbie to the Arduino world, but have some programming experience in Java.
I'd like to build an Arduino-based open-loop lap timer for a 200ft slalom course. There would be an infrared sensor at each end of the course whose path would be broken as a car enters and exits the course, signaling the start and stop time of each run.
Anyone have experience or advice for using the Arduino in this way? A concern of mine: will the length of the course be an issue? Rather, will the length of wire (100ft) from each IR sensor to the Arduino cause any problems with signal attenuation?
Many thanks for your time and advice.
