WiFi Bulb

Essendo possessore di una Canon 100D e volendo fare dei filmati TimeLaps, ho avuto la necessità di creare un sistema di scatto multiplo e temporizzato e mi sono detto perchè non farlo con Arduino?

L'ESP8266 crea un access point Wifi al quale posso accedere con qualsiasi dispositivo.

Mediante l'interfaccia Web posso programmare il bulb con le opzioni :

  • Modalità messa a fuoco.
  • Tempo di messa a fuoco.
  • Tempo di bulb.
  • Tempo intervallo.
  • Numero di scatti.
  • Tipo HDR.
  • Tempo intervallo HDR.

Ho inserito un LED RGB che cambia colore in base allo stato del bulb

  • Arcobaleno - Bulb fermo.
  • Blu - Messa a fuoco.
  • Rosso - Scatto/Bulb.
  • Verde - Tempi di attesa / Intervalli.

E' possibile variare la luminosità del LED.

E' possibile richiedere lo stato del bulb con.

  • Il tempo trascorso da quando il bulb è acceso.
  • Il tempo di inizio processo.
  • Il tempo che è trascorso da inizio proceso.
  • Il tempo previsto per la finedel processo.
  • Lo stato corrente : fuoco / scatto / intervallo.
  • Il numero di scatti effettuato.

Materiale usato :

  • 1 - ESP8266
  • 2 - Optoisolatore EL817
  • 1 - LED WS2812
  • 2 - Resistenze 100 ohm
  • 2 - Resistenza 1K ohm
  • 1 - Regolatore di temsione LM317
  • 1 - Condensatore da 100 uF
  • 1 - Trimmer da 2K ohm
  • 1 - Connettore USB-A
  • 1 - Jack da 2,5 stereo
  • Vari strip maschi e femmina
  • Vari cavetti
