Se non dovessi riuscire a non venire, il luogo di questa specie di fiera, mi rivolgo a chi e' del luogo, e' fornita di parcheggio ? vicino ? economico ?

Solo parcheggio a pagamento, e da fine Agosto il comune ha tolto la tariffa agevolata di 4 Euro per tutta la giornata, ora si paga 1,5 Euro per ogni ora di sosta.

Volendo usufruire delle strade ferrate, cosa che noi del sud conosciamo bene (visto che quando l'abbiamo montata per la prima volta nel regno delle due sicilie, voi a roma eravate ancora con i cavalli), c'e' una stazione vicina ? ferroviaria o a limite metropolitana ?

Se c'è una cosa che funziona abbastanza bene a Roma sono i mezzi pubblici, dalla stazione Termini prendi  la linea   METROA (direzione Battistini) per 16 fermate, scendi a Flaminio, circa 100 metri a piedi per arrivare alla fermata bus Flaminio, prendi la linea 2 (direzione Mancini) per 4 fermate, scendi ad Apollodoro e sei praticamente arrivato, circa 200 metri e sei all'Auditorium Parco della Musica.
Con lo smartphone puoi consultare il sito di ATAC Roma per avere tutti i dettagli sul percorso, non prendere un Taxi perché come minimo ti costa 30 Euro arrivare all'Auditorium dalla stazione.

Der Schaltplan passt soweit.

Versuche dir gleich anzugewöhnen, Masseverbindungen nicht mit Leitungen, sondern mit Massesymbolen darzustellen, ebenso die Versorgungsspannugen, das macht das lesen des Schaltplanes leichter.
Das kannst du übrigens auch mit anderen Leitungen machen: Verbinden mit Labels macht es oft übersichtlicher.

Ausserdem würde ich dir empfehlen, an die 12V noch einen KerKo zu hängen, das macht das Netz ruhiger.
Ein Kondensator an der Versorgung ist nicht immer nötig, spart dir aber unter Umständen viel Zeit bei der Fehlersuche!

Grüße
Gunther


P.S.: ich mag Fritzing.

Do you have the NewPing library installed?

Okay - I have made some changes to my code and if you have a second, I appreciate any thoughts! 
I think that everything I would have commented on has been covered.

For a simple program using functions and passing variables back and forth is an overhead but they are good tools to have in the locker for larger projects in the future.  Functions provide a method of avoiding the need to repeat common code and judicious naming of functions and variables can help enormously in understanding a program especially when you go back to it after a period of time.

Now, I wonder, can we find a reason to use pointers in your program and really up the ante ?  smiley

My guess is that VB is a lot like VC#?

Then you need to put the
Code:
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

        Dim s As String
        s = SerialPort1.ReadLine()
        TextBox1.Text = s
in a tick timer. Right now it just reads it once during startup and then nothing.

Also, inside the timer, put:
Code:
            if (SerialPort1.BytesToRead > 0)
            {
        Dim s As String
        s = SerialPort1.ReadLine()
        TextBox1.Text = s
}

there. Now it just checks if there is data in the buffer. If there isn't any, it skips the reading part.

I suspect some wrong connection on the relay shield. Even if the OP has connected everything correctly, the relay shield may be faulty and could have shorted out arduino. End result: need one more UNO, careful with that relay shield and make sure it's not shorting a second UNO.

it says i have 1169 free memory

I inserted serial print data in my code and the function calls without pushing buttons is

void loop
Sensorupdate
menustart
mainmenudisplay
BoxSelector

when a button is pushed the function call is as follows (from visual inspection)

debounce
buttontest
menubuttonactionreader
MainMenuButtonAction

the serial print is suppose to print zero for button 1 and 1 for button two

the serial print prints zero fine but after it prints one once and then back to zero it can never go back to one, the program also starts registers the second button as button one and prints zero

Da ich einer der jenigen bin die das Rad neu erfinden wollten, melde ich mich auch nochmal zu Wort ;-)

Ich denke für einen Anfänger nicht umsetztbar das es sehr gut fliegt. Irgendwie in die Luft ja aber mehr nicht.

Du hast es ja in den anderen Threads oft genug betont und recht behalten. ;-)

Ich bin mittlerweile auch "fertig" mit meinem Copter Projekt, habe das gute Stück sogar unter Verlust diverser Propeller irgendwann in die Luft bekommen. Richtig fliegen, das es auch nur halbwegs Spass macht, konnte ich das Ding leider nicht. Nachdem ich mich auch immer weiter an Code-Schnipseln von Multiwii orientiert hatte habe ich dann irgendwann aufgegeben, irgendwas  schlecht zu kopieren macht mir auch keinen Spass. Mittlerweile fliege ich Multiwii. Ein paar Kleinigkeiten habe ich dort schon meinen Vorstellungen angepasst, habe das waren immer nur Dinge bei denen der Copter nicht gleich abschmieren kann.

Das Thema Copter bauen und auch fliegen habe ich wirklich ziemlich unterschätzt muss ich gestehen. Auf der anderen Seite haben das andere Leute ja auch schon hin bekommen siehe -->http://forum.arduino.cc/index.php?topic=184503.0. Positiv bei der ganzen Sache, ich habe ne Menge gelernt, das tüffteln hat Spass gemacht und ich habe eine neues Hobby von mir entdeckt ;-)

Gruß

Are you worried about the voltage difference between arduino (5V) and xbee (3.3v)? At a low baud rate (9600) you can just use resistor voltage divider to convert arduino output into 3.3V. Connect xbee output directly to arduino. It can read 3.3 as logic high.
