Arduino Flash Trigger - sound / laser

[cthrough007]

How did you connect the flash to the arduino?

All You need to do is close the cable. I use a Solid State Relay like this one: goo(dot)gl/oe7yX

Very nice build! More professional than most I've seen with the LCD display and keypad to control features and the calibration all set independantly.

I would be very interested in a documentation of the schematic and code!

thanks for sharing.

hi do you have a link to code- please post it. alos what captor did you use for the laser part..

Thanks

@castelsylv I use a simple LDR (photoresistor) to measure the laser beam.

When the measured value is lower as some callibration value, then I trigger the flash.

An example Code:

int normalLaserValue = 0;

void setup()

{ //calibration int normalLaserValue = analogRead(0);

}

void loop()

{ // 20 ist the trigger sensibility if ( analogRead(0) < (normalLaserValue - 20) ){ triggerFlash(); }

}
