Custom Circuit (LED Ring Light) Requirements
I have an LED ring light to fit over our Axis camera on the robot, which requires 12V. For power I'll connect to the PDB with a 20 amp breaker, but I wanted to be able to use a DIO to toggle the light on and off (save power, not be distracting while testing).
To do this I want to use an NPN transistor then toggle the Base via DIO. To comply with custom circuit rules, what sort of protection do I need (if any)? I would think the LED's themselves would suffice as protection diodes.
