High Low signal to shut down light source instead of using shutter

Good day everyone.

My thanks to this community for your honourable work making it possible for simple folk like myself to build printers.

I am working on a machine that utilised a projector whose arc bulb will be replaced by a uv led (projectors with dead bulbs are cheap).

this means that it's super easy to turn off the lamp using a relay (mechanical or a transistor) thereby making the use of a servo operated shutter redundant as the lamp can be powered off and restarted easily.

I wish to request that a pin on the gpio be configured as a IO output to switch a relay mechanism that will allow control over the lamp state.

My kindest regards to all and salutations from South Africa.

You can use [[GPIOHigh]] keyword to turn on/off switch through nanodlp.
