Water Drop (Simple)

This is the very basic code to catch a water drop on camera. Why is it called basic? Because you have to set your parameters in the code, there is no menu or PC application, that allows you to change the parameters mid-run. You have to change the parameters, so they match to those of your mechanical construction. Remember, that all paramters are in millimeters or milliseconds. You can also determine, if the mirror-lockup is enabled.

1 How it works

After you changed all parameters depending on your physical construction, you can upload the script to your Arduino. Note, that you can change the adjust time afterwards, by sending the Arduino the time in milliseconds via the serial monitor. If you hit the start button, the Arduino will get the sensor signal and uses it as trigger-reference. If the mirror lockup is enabled, the camera will be triggered once, to pull the mirror up. After this the LED on the Arduino will go high, which is the signal for you to let the water drop fall.

That's all, just a very simple sketch to chatch a water drop.
