In the movie “Middle Men”, two guys decide to start an online porn subscription service (which is allegedly how online credit card transactions started). They built a gadget that either whistles, chimes, rings (along with other noises) every time there is a new incoming order.

We don’t do smut… but that movie inspired us to create our own similar gadget for Insteegram.com.

With the recent Likeacoupon deal, Insteegram has been getting a lot more sales and visitors. So, we decided to rig up this gadget using:
1 arduino uno
1 breadboard
1 arduino ethernet shield
1 yellow LED
1 330ohm resistor
1 piezo transducer
and some hook-up wires.

It works like a charm:



Everytime there’s a new user, it plays a lower octave C note.
Everytime there’s a new incoming order, it plays a upper octave C note.
Whenever there are unfulfilled orders, the yellow LED light stays on.

This gadget is totally unnecessary and a little annoying, but it’s definitely COOL!

Almost forgot…. here’s the crucial source code that makes this device run:

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

//Serial.begin(9600);
if (Ethernet.begin(mac) == 0) {
//Serial.println(“Failed to configure Ethernet using DHCP”);
for(;;)
 ;
}

//Serial.println(“connecting…”);


}

void connectToServerA()
{
