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.
