Thanks for all of the suggestions from all of you. As the 3 input port had been occupied by 3 analog sensors (not light sensor, but declear as light sensor in program), so I do not think overloading a sensor is a good idea. The suggestion of (...) (24 years ago, 16-Feb-01, to lugnet.robotics)

A simple on/off sensor can be placed in series or parallel with other on/off sensors however analog sensors cannot. It should be pointed out that if you do group sensors, it becomes impossible to determine which one was actually triggered. This (...) (24 years ago, 16-Feb-01, to lugnet.robotics)
