Purpose:
My home temperature with arduino!

URL:
http://sgez.homeip.net:888

Tools:

• Internet connected router
• Portforwarding to port 888 for ip 192.168.1.99 (arduino ethernet shield ip address)
• Arduino Duemilanove
• Arduino Ethernet Shield
• A buzzer
• Ethernet cable
• Cable connectors

Difficulty / Time to complete:
Intermediate / 30 minutes

Schematic / Arduino code:
The following abstract schematic was used:

Tutorial: First Arduino program - Kit's lights

Purpose:
Flash 4 leds from right to left and left to light.

Difficulty / Time to complete:
Beginner / 5 minutes

Tools:

• Arduino board (tested on duemilanove)
• 4 LEDs
• 1 switch
• 1 10K/.25W resistor
• Workstation with Arduino 0.017 or higher
  

Arduino code:

int leds[]={10,11,12,13};   //pins with leds
const int dl = 75;          //delay between moving
const int btn = 9;          //button pin
int btnS = 0;               //button state
int i=0;                    //general purpose counter

void setup(){
for(i=0;ipinMode(leds[i],OUTPUT);
}
pinMode(btn,INPUT);
myflash(leds,sizeof(leds),dl,false);
myflash(leds,sizeof(leds),dl,true);
}

void loop(){
btnS = digitalRead(btn);

if(btnS == HIGH){
myflash(leds,sizeof(leds),dl,false);
myflash(leds,sizeof(leds),dl,true);
delay(250);
}
else{
for(i=0;idigitalWrite(leds[i],LOW);
}
}

//myflash function: flash an array of pins to the R or L
void myflash(int arr[],int size,int delay1,boolean reverse){
int j = 0;
if(reverse==true){
for(j=(size-1);j>=0;j--){
digitalWrite(arr[j],HIGH);
delay(delay1);
digitalWrite(arr[j],LOW);
}
}
else {
for(j=0;jdigitalWrite(arr[j],HIGH);
delay(delay1);
digitalWrite(arr[j],LOW);
}
}
}

The final product (video):

Arduino - first impressions

Open source at its best (both in hardware and software)!

Pros (+):

• Nice, compact design
• Usb interface
• Broad source code from arduino.cc and other sites/blogs
• Ready-made IDE/usb drivers
• Linux/Mac/Windows portable (both IDE and PC-to-Arduino dev)
• Easy PC-to-Arduino dev via the Processing Language
• Very cheap!
• Lots of shields available!
  

Cons(-):

• Linux driver installation requires some more steps
• Addictive
• Must buy more shields (who wants to blink leds all day long?)!
  

I dual boot on my Eee PC 1000h (Windows Xp/Ubuntu 9.10b):there is a remarkable difference from the IDE to the sketch loading on the Atmel.
