Buton arduino

[loleksibolek]

Acum ceva timp am modificat un sketch (adresa de unde e luat e la începutul lui) pentru a-mi acționa un servomotor in funcție de un cititor rfid.De mers merge bine,memoreaza si șterge carduri ok,acționeaza servomotorul, dar m-am lovit de o problema: dacă panoul cu cititorul rfid și afișajul  e în afara ușii(asta face,acționează un zăvor cu servomotorul)din interior nu pot să deschid ușa .Așa că m-am gândit sa-i pun un buton care la apăsare să acționeze servomotorul câteva secunde apoi să-l aducă in poziția de închis.Eh,nu știu ce și cum dar nu-mi iese deloc,maxim ce am reușit e să citească la început butonul si să acționeze , apoi pauză...Deci dacă cineva are timp și se pricepe...

Butonul l-am pus la pinul 2,deci am nevoie ca la apăsarea butonului să  acționeze sevomotorul  câteva secunde(Servo1.write(55)) apoi să revina la 0.

Modifici linia asta:

if ( findID(readCard) ) {        // If not, see if the card is in the EEPROM

în

 

 

if ( findID(readCard) || digitalRead(2) ) {        // If not, see if the card is in the EEPROM

Asta dacă pinul 2 e tras spre alimentare ( 1 logic activ)

altfel inversezi condiţia de citire a pinului:

digitalRead(2) == LOW;
