Un saluto a tutta la comunity.
Al contrario di chi pensa che l' open sia solo un modo per poter ottenere informazioni e poi tranne profitto, volevo condividere una mia idea su di un progetto alquanto "strano".
Creare un orologio a lancette con arduino.
Pensandoci un pò, sono arrivato alla conclusione che sia fattibilissimo, senza usare marchingegni o artifizi particolari.
Certo un pò costoso rispetto ad un orologio da parete, ma comunque credo originale.
Userò un arduino uno, 3 servo motori, tre pulsanti e tre resistenze da 10k(non per forza necessarie) come per LCD.
Inizialmente pensavo ad uno o più motori passo passo, ma credo non semplice come realizzazione del meccanismo di posizionamento, mentre sapevo per certo che i servomotori si posizionano dove voglio con un range di ben 180 posizioni ed in modo molto preciso.
Allora dopo l'acquisto dei servo, ecco il mio primo prototipo che ho chiamato ArduoServoTime.
Buon divertimento, e per chi è interessato, via all ' evoluzioni creative.
