Nicu FLORICA (niq_ro): Afisaje LED cu 7 segmente si.. Arduino (IV)

luni, 16 decembrie 2013

Afisaje LED cu 7 segmente si.. Arduino (IV)

Fata de articolul anterior, acum am introdus facilitatea de a regla manual orele si minutele, la ceas...
Schema de baza, este aceeasi, doar ca se adauga partea de reglaj (3 butoane, unul cu care se reseteaza datele, unul pentru minute si unul pentru ore). Cand se face reglajul, butonul de resetare date trebuie tinut apasat... partea aceasta am gasit-o la http://www.bristolwatch.com/arduino/arduino_ds1307.htm

Un filmuletul demonstrativ se numeste ceas cu reglaj manual cu Arduino si afisaj LED cu 7 segmente multiplexat, respectiv manual adjust for RTC clock with Arduino and 7-segment LED display (cu tentativa de explicatii in limba engleza):

PS: Am desenat toata schema sa nu apara confuzii:

Sketch-ul este urmatorul:

Foarte de ajutor articolul acesta de la tine, multumesc. Am observat ca trecerea de la ora 9:59 la ora 10:00 se face afisind 0:00 in loc de 10:00. Dupa un minut, se afiseaza corect 10:01. Cred ca e din cauza ca nu este tratata si situatia cand timp = 1000, e doar timp > 1000

Hello sir please i need help, why is it when the power of the arduino goes off and come back the time return to 0:00, is there anything i have to do because am using DS1307 rtc
and it suppose not to be set again because the rtc is backing it up.

Se poate integra reglajul timpului in modul de temperatura si afisaj??
Adica http://nicuflorica.blogspot.ro/2013/12/afisaje-led-cu-7-segmente-si-arduino-iv.html si http://nicuflorica.blogspot.ro/2013/07/afisaje-led-cu-7-segmente-si-arduino-ii.html.Ca am reusit doar sa modific pinii si tipul senzorului din DTH11 in DHT22.
