First what does this line exactly do?
IPAddress ip(192, 168, 1, 177);

This creates an ipv4 address for the w5100. It is the ip of your ethernet shield.

Re: Audio player - LCD and buttons

Posted: 10 Apr 2013 02:46 AM PDT

My next question is for the LCD.

I use a standard 16 x 2 LCD with the Liquid crystal library.

With this code, I see the terminating null character.
How can I shorten the array that it don't display this character ?

I tried to define an array for the lc...

Der vorteil von einem Arduino und dem Seeedstudio Shield ist, daß man es draufstecken kann. Nichts verbietet Dir aber die Kontaktstifte auszulöten und das Shield mittels Kabel am Lilipad anzuschließen.

I think you need to use a capital S for the file extension if you want gcc to know to use the C preprocessor on the file (which it needs to do for the #include and #define.)

Re: Astable triggering monostable

Posted: 10 Apr 2013 02:17 AM PDT

Why don't you just build an astable version with a very low duty cycle? 2 seconds high, 120 seconds low, that's a duty cycle of 1/60. You will need only one ne555.

Since the duty cycle of a ne555 is always above 50%, you could make a duty cycle of 59/6...

Hmm..
Ja, wie es derzeit aussieht, wird es wohl auf eine non-Lilypad-Lösung hinauslaufen.
Oder meint ihr, man könnte quasi eine Hybrid-Lösung anstreben, in der normale Arduino-Module als auch Lilypad-Module genutzt werden?

Liebe Grüße und danke schon m...

Does your code do what you want?

If so what is the point in asking a question?

If not, please explain what you want it to do and what it actually does.
