Questions on programming/using Photoelectric sensor

-

hello all! making automated can crusher , using "atc" photoelectric sensor 10-30v dc sensor using 12v power supply power both sensor , arduino. question have advice make program work properly? want sensor tell when can present , activate program. have program setup without sensor or switch period. curious on best way go using start program? have searched through forum see how go doing , couldn't quite find suit application. figured best forum considering amount of experienced users arduinos. advice or ideas appreciated! :)

hello,
the project sound pretty basic me. need periodically turn light beam on, test if being received @ sensor. if is, there no can , nothing needs done. if light beam not detected, there can start crushing. need step x times in 1 direction , x times in other direction.

when done, use delay , wait second or 2 before testing again can...

once far, consider removing delay , using sleep mode instead.

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!
