Easy games, part 2 - Hot Game

Here again writing on Stica-Lab on the "Easy Games" section...,

This second session is dedicated to build a game that I called "hot game"; I want to build a board with few led and two temperature sensors. 
You can play in two, touching the sensors and Arduino will show you who is the hottest one :) by lighting the leds, green leds mean that there is the same temperature on both sensors.
The buzzer make the game a little bit more nice...adding the sound :)

What we need:

1) Arduino Uno board;

2) breadboard;

3) 8 led (4 reds, 2 yellows, 2 greens)

4) 8 resistors 220 ohm

5) 2 LM35 (temperature sensors)

6) buzzer

7) few cables
8) code: you can download it from here

wires connection:

Here the photo (all the necessary components are placed and connected on the breadboard):

Here the video

See you to the next post :)
