I was looking for automatic cat door, but with a real door. Then I saw the M5Stack Shop and decided to try it by myself…

Thats the result from my first project with M5-Stuff and UiFlow! Not yet looking good. But first it has to work for a few days before I fix all the cables.

The door opens only about 15cm! Not like the picture. And stays open for 15 seconds. With a led stripe as a countdown/up

Here as a video

Material:
Core2 with DinBase and a 12V power adapter
1 PaHub ( next to the Core)
1 PbHub ( next to the Core)
2 Pir Units ( 1 inside and 1 outside with a pipe around for smaller angles)
2 Limit Units (1 on the open door and 1 above left)
1 TOF Unit (1 on the sliding triangle)
1 DayLight Unit (behind the robe for the brightness)
1 Ultra Sonic ( upper left)
2 x 360° servos
1 Groove Hub
1 Led Stripe (just for fun)
1SD Card for Door-Status-Logfiles
Some lego bricks and gears
And a lot of cables

And of corse some home working materials

We got 2 chipped cats. The already ordered Rfid Units works at 13 Hz not at 134.2 for the cats. So I cant „read“ which cat is inside. They leave on the right. I planned to make a tunnel with 1 unit at the entrance and 1 at the exit. With the ID and the timestamp I can see hows in or out. If someone knows how to realize that, please tell me!

Important for me:
The door will be still usable as normal!
No Movement when the door is locked, because of damage.

Thanks for that forum!
