[Yatelian] Universal infrared remote control

Universal remote control based on Atlink CB3S, 0 code (no need to write any code, just buy the components and solder them)

Let’s talk about the purpose of the production first: in today’s hot weather, people can’t live without air conditioners, but they can’t be turned on until they get home, so it causes the trouble of feeling that the air conditioners haven’t worked even after returning home for a long time.

I tested this picture to see if it can only be used on LAN. If so, it's all in vain.

Let the module be connected to WiFi, and the data test on the mobile phone can be used, perfect.

I can solve the problem by turning on the air conditioner on the way home. It’s very cool and refreshing when I get home.

Let me mention it again, it’s really nice not to have to write code.

Finally, I would like to give you some suggestions:

1. The infrared receiver can be placed on the back, or in an inconspicuous place, because it is basically not used.

2. Remember to connect the pull-up when using it. The receiving head from Taobao can be used.
