Relay logic

Relay logic is like a big switchboard that helps control different machines or equipment. Imagine that you have a lot of different toys that you want to turn on or off, but you don't want to press each button for each one. Instead, you can have a system that uses a bunch of switches to help you control everything all at once.

Relay logic is like that system. It uses tiny switches called 'relays' to help control bigger switches for things like lights, heaters, motors and more. Each relay has two sides - one that is turned on when electricity goes through it, and one that is turned off.

So if you want to turn on a light, you might press a button. But instead of the button directly turning on the light, it sends electricity through to the relay. That switch then turns on and sends electricity to the bigger switch that controls the light.

It's like a relay race, where each runner takes a turn towards the finish line. The buttons or sensors are like the runners, and the relays are like the batons that they pass to each other. Each little switch has a purpose, and together they work as a team to control different machines or equipment.
