Newbie project: distance-brightness correlation

Projects General Guidance
1

Hey all,

I'm new to Arduino so I was wondering if I could get some pointers on how to go about this project:

Basically, 3 LEDs are controlled by one sensor each (the Sharp GP2Y0A02YK0F). The LEDs are brightest when an object is closer to it, c. 10cm, but is dimmest when an object is 1m away, and the LEDs are off when an object is more than 1m away. The LEDs operate independently of one another.

Any words of advice? I'm basically familiar with Arduino but only copying recipes and sketches; I have never created something from scratch, so absolutely any help would be vastly appreciated.

Start with one sensor and one LED.
You probably should look at the "map" function.
