aleda5859 Inserito: 19 settembre 2004 Segnala Inserito: 19 settembre 2004 Salve a tutti... sono tornato Avrei bisogno di costruire un metronomo con un uscita cuffie e magari un display a 7 segmenti che conti i battiti [ 1...2...3...4 ...1...2...ecc..]Avete qualche idea o schema per caso?Vorrei alimentarlo a batteria.

aleda5859 Inserita: 19 settembre 2004 Autore Segnala Inserita: 19 settembre 2004 Felice di sapere che tu l'abbia costruito.. non è che potresti passarmi qualche schema? o consiglio ?In sostanza dovrei creare un'onda quadra corrispondente ad un certo clock che permetterà di emettere il suono.Questo posso farlo con gli integrati ma il suono come lo faccio uscire?

aleda5859 Inserita: 27 settembre 2004 Autore Segnala Inserita: 27 settembre 2004 Wow!Ti ringrazio ma io intendevo costruirlo elettronico.Già che ho aperto la discussione scrivo come ho definito la cosa tante volte dovesse servire a qualcuno.Con un NE555 ho fornito l'onda quadra per il "tic" del metronomo ovviamente regolabile in frequenza da un potenziomentro. Ho collegato poi questo circuitino ad un amplificatore per cuffie/casse dato che chi dovrà usare il metronomo lo vuole appunto "nell'orecchio" e bello sparato da lì ho colllegato l'entrata cuffie ed un piccolo altoparlante.Insieme ho collegto un transistor interruttore che grazie all'onda quadra dell'NE555 collegata alla base mi accende e spegne a tempo un led Flash blu.Infine per segnalare lo stadio di ON/OFF dell'apparecchio ho collegato all' swich di accensione un led rosso.Così ho ottenuto la segnalazione acustica della cassa ed in cuffia eventualmente con volume regolabile dal piccolo preamplificatore + la segnalazione visiva del Flash che si accende e si spegne a tempo.Se foste interessati vi posto alcune foto appena assemblo il tutto... ancora lavoro su breadboard.Ciao a tutti!
