I have an electronic dog door that is triggered by an ultra sonic collar on the dog:
The end game is to be able to trigger this door using an arduino.
The door works great from an opening/closing standpoint and sealing out the outdoors. The problem with this detection method is that the collar is bulky for a small dog, requires custom batteries, and is expensive to replace. What I want to do is hack the door to also be triggered with an arduino and an RFID sensor.
There is a button on the door frame that will open the door. Holding it down keeps the door open until you release it. My idea to hack the door is to tap in to that physical button and simulate a push. My arduino will be a separate circuit and could even have it's own spearate power source. I'm not good with circuts but I'm really good with coding. I can code an arduino to detect the rfid tag. But I need to know what circuit I would use around this switch so that I can close and open the button from code. I would then solder my connection to each side of the switch.
Possibly I'm not providing enough information.
