Step 2: Connect the Relay Module to Your Projector
Connect the relay module to your projector’s power supply. This typically involves soldering wires or using a breadboard.
Step 3: Create a Blank Screen Switch
Create a switch that triggers the relay module to turn off the power supply to your projector. This switch can be a simple button or a more complex circuit.

What is the purpose of blanking a projector screen?
Blanking a projector screen is a process that involves turning off or dimming the projector’s light source to create a blank or dark screen. This is often necessary during presentations, meetings, or events where the screen is not in use, but the projector is still on. By blanking the screen, you can conserve energy, reduce heat generation, and minimize distractions.
Blanking a projector screen can also be useful when you need to pause a presentation or video and want to focus the audience’s attention on something else. It can also help to reduce eye strain and prevent the screen from becoming a distraction. Additionally, blanking the screen can help to prolong the lifespan of the projector’s lamp by reducing the amount of time it is in use.
