The top breadboard was used becaude the 2.5mm jack would not fit at the edge of the larger one. i will be adding to the code as i work on the project.

/* on auto focus and a long HIGH delay the camera focusus and then shoots the exposure dialed in on the camera. either manually or shooting in any auto exposure setting.

on auto focus and a short HIGH delay the camera sometimes does NOT receive the shutter trigger long enough to fully focus. the result is the camera trying to focus for the duration of the HIGH delay and never takes a shot

on manual focus any HIGH delay works, though it is recommended to use a short delay.

bulb mode will stay triggered as long as the HIGH delay is.

Built using a 2N2222 transistor.

void loop(){

 for (int val = 0; val < 10; val++ ){ //this runs 10 times just as a test
   digitalWrite(2, HIGH); //trigger the shutter
   delay(5000); //how long the shutter trigger is HIGH
   digitalWrite(2, LOW); //turn off the shutter trigger
   delay(5000); //delay until next shot
