I have a project where I am using a DK to set a pin (momentarily) to HIGH to trigger a camera. The challenge is that the camera is about 25 feet away so the voltage received by the camera becomes too low.
How can I boost the voltage to say 8V or 10V so that I can get at least 4-5v at the camera? I tried voltage step-up regulators but they suffer from an unacceptable delay in boosting the voltage.
Any help is appreciated.
