Temperature Recording Arduino Robot

My son and myself made a little arduino robot that records temperature. He wanted me to draw a robot, I wanted to experiment with blinking LEDs relaying data so a plan was hatched. The way the LEDs work is as follows: Green = lowest temperature recorded, Yellow = highest and Red = current temperature with all readings being in °C.

Step 1 The Ingredients

The ingredients are rather simple and comprise of the following:

Arduino 
LM35 temperature sensor
3 LEDs (1 x red, 1 x yellow, 1 x green)
9v battery and lead
Small breadboard and the usual wires
Small cardboard box

IM BUILDING THE SAME PROJECT FOR MY CLASS, HOW DO I KNOW WHAT THE CORRECT WIRES ARE GOING TOO?

Hi there,

The LEDs work off pins 11, 12 and 13 with 11 being the lowesr, 12 the highest and 13 the current temperature.

Regarding the temperature sensor, as well as the 5v and ground pins, it feeds into analogue pin 0. I can draw a quick diagram if you wish?

Hope this helps.

Here you go. Let me know how you get on.
