Common ground

[sven]

Is it correct that both the 9V, 5V and 12V parts of the cirquit all have common grounds?

For example, do the LEDs and Solenoid valves all use the same ground connection? Or do i need to keep those separate?

Hi Sven,

yes. The ground is common for all those parts.

The only part that is separate are the camera and flash triggers and these are separated using optocouplers.

Thanks, makes the PCB a lot simpler 🙂
