Problema no circuito arduino+solenoide+rele+rfid

[GabrielAssis]

Bom dia pessoal, sou novo no forum e preciso mesmo da ajuda de vocês.

Já tentei de tudo, desmontar e remontar o circuito e nada adianta. 

Fiz um protótipo de um porta-chaves que tem uma trava solenoide 12v na porta, e quando aproximo do módulo RFID o cartão autorizado, o arduíno manda o sinal para o rele e a trava libera, até ai ok, mas depois não libera mais, parece que não esta fechando a chave, algo assim.. e não sei como agir

Em anexo o circuito montado

[.if]

Olá... Publique o fonte do programa. Pelo sintoma, parece que esqueceste do loop principal.

Oi Isadora! Obrigado por entrar em contato para me ajudar.. 

Quem mais puder me ajudar, seria muito bom! valeu galera
