Controller plafoniere fai da te Arduino alla portata di tutti
 
Ciao a tutti.
Se state pensando di realizzare un controller per la vostra plafoniera led autocostruita e state pensando ad Arduino questo articolo può fare al caso vostro.

Ero alla ricerca di un controller per la mia plafoniera ed avevo pensato ad arduino solo che una volta acquistato, anche se ho un minimo di conoscenza nella programmazione, non avevo voglia di perdere mooooolte ore per realizzare un codice.
Quello che serviva a me era poter gestire 2-3 canali con effetto alba-tramonto, mi sono messo a cercare online e sono incappato in un controller(non dico il nome) in grado di fare questo.
Ed ecco l'idea, perchè non realizzare l'hardware sulla base del codice anzichè viceversa?

Perciò analizzando il codice(disponibile online perchè open source) sono risalito all'hardware necessario, ed ecco cosa serve per realizzare il vostro controller :
-Arduino uno
-RTC ds1307
-Display 1602
-4 switch button
-4 resistenze 10kOhm
-1 resistenza 2.2kOhm
-1 resistenza 100 Ohm
-1 transistor BC547

Ecco lo schema per collegare tutti i componenti

L'unica cosa non corretta nei collegamenti sono i pulsanti, cioè manca il disegno della resistenza.
Ecco come realizzare un pulsante digitale:

Per quanto riguarda l'RTC acquistatelo già su pcb con pila e non dovrete fare nulla se non collegarlo ad arduino senza dover assembrare tutti i componenti come in figura.
Io ho realizzato tutti e 4 i pulsanti su una millefori rettangolare in modo di avere i pulsanti già tutti su uno stesso piano tutti insieme e con la disposizione che si desidera.

Una volta realizzato l'hardware, basterà collegare il dispositivo al pc, e caricare tramite l'ambiente di sviluppo Arduino 0022, e mi raccomando Arduino 0022 e non i successivi, il codice seguente:

Penso di aver detto tutto, Buon divertimento, ecco quello che ho realizzato io

Per ringraziare qualcuno c'è il pulsante apposta. Thanks

Visto le numerose richieste di aiuto che ci sono sul forum riguardo ad arduino e mai nessuno che posta i codici ( mi sembra anche giusto visto il duro lavoro XD ) ho deciso di condividere questa piccola guida che può essere anche solo uno spunto visto che il codice poi può essere modificato a piacere, ma per chi è zero assoluto bella programmazione può andare bene

Grazie per la condivisione.

Qui si trovano altre informazioni. Io come prima cosa ho provato ha collegare il display LCD ma dopo un'ora di prove e il controllo dei collegamenti non sono neanche riuscito a far comparire la scritta classica scritta "Ciao Mondo".

Ho sbagliato a collegare il pin R/W. Invece che alla terra (GND) l'ho collegato a +5V (lato porte analogice. Secondo te ho danneggiato qualcosa?
Perché poi ricollegato tutto giusto non andava ancora >:-(

Cavolo dove hai trovato quel post..
Mannaggia se lo trovavo faticavo 20 volte meno XD..

Comunque allora sbagliare i collegamenti del positivo non è mai una bella cosa, però non è detto che tu abbia rovinato qualcosa..
Tu che schema stai seguendo per il collegamento?
Se stai facendo delle prove non usare quello postato da me ma uno classico che trovi su nei tutorial, perche cambiano i pin di collegamento e quindi anche quando li dichiari devono corrispondere a quelli a cui li hai collegati.

Segui questa guida per il collegamento del display per le prove

Ho seguito proprio quel tutorial nel link che hai messo tu.
Il mio LCD è un LCM1602C.
Comunque riproverò con calma a ripartire da zero. Spero bene...

matteociocca 02-01-2014 21:10
Tante volte basta un falso contatto e non va nulla..
Controlla le saldature, se è tutto collegato correttamente va per forza..
A schermo cosa ti esce? Si illumina?

grispa72 02-01-2014 21:17
Iniziamo dai componenti. Io ho un Arduino UNO REV3.

Poi l'RTC DS1307 è questo?
Serve pure la batteria (mi pare)?

Questo è il BJT NPN BC547.

Poi per quanto riguarda l'IDE cosa intendi per 0022? Quello che si scarica da qui?
