I found an interest in waterdrop photography quite a while ago. Leaving the faucet dripping into a bowl of water worked for a bit, but it was unreliable and not easily repeatable, so I decided to make this controller. It controls a solenoid valve, my camera shutter trigger, and a flash trigger. Potentiometers are used to set the interval between two consecutive drops, the period the valve is opened for (to control the size of the drop), when the camera shutter is opened, and when the flash is fired. It was a fun project for 16-year-old me and helped to introduce me to the world of embedded design. Click the button below for schematics, code, and a gallery showcasing the project.
