Join Michael Lehman for an in-depth discussion in this video Understanding effectors, part of Android App Development: Internet of Things.
- Again, remembering our four components of a thing,…sensors and/or effectors, compute and connectivity.…Let's take a look at effectors.…Effectors are things that allow you to actually…make something happen in the real world.…Effectors can be audible.…They can be speakers and headphones,…beepers and buzzers.…They can be visible.…LEDs, a flash for a camera, a laser pointer.…They can be tactile, such as a motor…that makes a wheel turn, or haptic,…which is a special kind of motor…which is like the buzz on your device.…
A servo which is another kind of motor,…except that is has very precise miniature movements…so that you can put it at exactly 75 percent or 23.3 percent…and you can use that to control various things…that open and close just a large amount…or a small amount `in very precise ways.…Then relay, which is how you can use a switch…to control a high voltage device…with a log voltage microprocessor based system.…Finally, they can be invisible or inaudible…such as infrared, which you can use both…to control other devices or receive messages.…
