DIY physical webcounter notifier with Arduino

To be notified every time his website received another visitor, Instructables user ‘janwil’ used an Ethernet-enabled Arduino board, a servo, LED numerical displays, an RGB LED, light-sensor and a “lucky cat” to create a physical notifier that waves the cat’s arm upon each visitor – as it is pushed by the servo. The light sensor is used to determine whether it’s day or night, and the physical arm movement won’t occur at night to keep things quiet. In this case the RGB LED illuminates instead of the arm being waved, for example:

 

A simple yet fun use of the Arduino platform. For complete instructions click here. And for more, we’re on twitter and Google+, so follow us for news and product updates as well. 

When putting together your next Internet-enabled Arduino project – save time, space and money with the Freetronics EtherTen. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket, full USB interface (so you don’t need a costly FTDI cable just to upload a sketch!) and supports optional Power-over-Ethernet.
