This little rig infact interfaces via USB to your PC clock and generates hours and half hours dings on a real bronze bell. Great stuff to bring into your office and surprise then amuse then annoy your helpless friends.
From these pages I already showed something similar where a serial port was used instead of USB. Today most PCs lack of a serial port and with this design USB serves also as power source.
Arduino is at its core and interfaces to the PC clock with a simple Processing sketch, its natural counterpart by design.
Step 1: Please, a video !
For some reasons I couldn't merge it here directly.
The audio is awful because of the camera's poor microphone. It should give a good idea though.
Step 2: Forewords
1: it is made in Italy.
2: in case of troubles tha community is there: for sure someone else has had my same
3: anyone with little or no software and hardware background can have a project running.
4: gives instant gratification : upon receiving the kit anyone can have a blinking LED driven
by a RISC processor, not bad.
5: the credits.
6: in case of serious problems I can blame someone else.
7: it is made in Italy.
Done with with the Ad, after years of working around the problem of not having a real Arduino board and wiring fake-ups, I finally bought one.
This contest is a great way of putting my 35 euros at work.
The picture shows Arduino along with a same sized breadboard to host the veeery simple hardware needed to complete the project.
