I think many have seen small infrared remote controls that are usually bundled with LED strips to control them and of course many know about infrared remote controls for controlling TVs, they all naturally work on the same principle, the remote sends a certain infrared signal, the photosensitive receiver receives it, processes, and the microcontroller or relay performs the desired function, for many this technology is already outdated, because there are a huge number of models with wi-fi and bluetooth controls, but at least they they are convenient, their minus is that both of these systems require constant energy and, as wi-fi is now saying, is even a little harmful to humans. Infrared remotes do not have such disadvantages, the radiation is too weak and last very short, and very little energy is required. It is about this economical option that will be discussed today.
This infrared receiver comes with a remote control, this bundle is designed for microcontrollers Arduino. On this basis, you can do a lot of different projects, I think they should not even be listed, because listing them will take a lot of time. The operating voltage is 5 volts, I think you can feed directly from the Arduino.
The cost at the time of writing is 45 rubles, the price can constantly change, so choose the best time for the order.
Shipping costs 47 rubles.
Well, thank you all for your attention and good luck in future projects, friends!
