Schematic for Pet Door

I am building an automated pet door which opens when the pet nears to entry or exit. While pet is entering or exiting, IR detects if pet is still entering or exiting by IR light. If there is beam break, door reverses, else closes. I just need to know if I got schematics right before I proceed to build.

Schematics

  1. IR Emitter and Receiver is used to sense IR break is the pet is in middle of door if break is detected then door goes back if closing

  2. Nema 23 stepper motor is used to open and close door

  3. Yet to figure out how the door opens when pet approaches as RF ID range is small and ultrasonic and IR may open door for anything which comes in front

Hello grcshekar71

Post the schematic in a format readable.
No one will open an unknown link!

Have a nice day and enjoy programming in C++ and learning.

It is beyond my intellectual capacity to follow the Fritzing diagram.

An Arduino is not able to power large loads.

A stepping motor is a poor choice for this, use a gear motor instead.

It will powered with 12 V DC so only connected in VIN

The Vin pin diode is not rated for very much current, suggest no more than 500mA.

Simple stepping motors do not have very much strength for moving things.

It is just 1/2 kg door I can power easy driver directly

stepper if not powered has no torque, so door will be easy to open manually. gear box or electro door lock recommended

pictured "IR" is remote control detector. not suitable as IR photoelectric sensor.

Which photoelectric sensor.do you recommend

something like this
