Tell us about yourself!
Read the instructable carefully. I have a video and 4 instructions on how to connect the ultrasonic sensor to the arduino. Please follow that for all of the sensors. I have created no explicit diagram, sorry.
Sunlight never reaches full luminance value of the photo-resistor. So, use the sunlight value as a constant value. Then if you shine a laser beam at it, its value will reach 1.
Thanks! Arduino to PHP, PHP to MySQL. Follow the above comment for the circuit diagram!

Did I mention IR somewhere? Sorry then. I was meaning to say laser sensors with IR. If the laser is fired directly at the IR sensor, then the IR will have an extremely high reading, nearly 1. That would be most efficient for dark situations. But ultrasonic works universally.
Repeat the same thing again. Hook up an ultrasonic sensor and repeat it.
Sure! It would be more accurate, but it would require more effort.
I pretty much used this code and everything was fine. Did you copy paste it?
