Alexa/Google Home Enabled Automatic DOG TREAT Dispenser
Introduction: Alexa/Google Home Enabled Automatic DOG TREAT Dispenser
We have two small dogs. At times, we need to leave them home alone for hours at a time, so I was on a quest to design a dog-treat dispenser that I could trigger from anywhere in the world! Using my Alexa App on my phone (or my voice in my home) I am able to simply say, "Alexa, give the dogs a treat" and this device triggers a horn to beep and a light to flash (giving the dogs time to come running from any room in the house) before dropping 2 dog treats for them to enjoy!
Supplies
I ordered a few simple supplied from Amazon. The rest were all lying around in my workshop. You could certainly improvise for your own design, but this is what I used to build mine. I've included links to each component below to help with your own build.
1. I used a 2x4 block of wood and some scrap plastic to build the frame you see here. The dimensions of the wood are 2x4 8" long You can use any height for the back support. Mine is 7" tall and its only purpose is to hold the optional light/buzzer. I used a nice dark ebony stain on the wood, linked below.
2. 120
The combination light/buzzer can be ordered below from Amazon. This component is optional and only used (in my case) to give the dogs advance notice that a treat is coming!
3. The toggle switch is also optional. I installed it simply to give me the option to turn off the buzzer/light (silence mode) which is helpful if you use this late a night while others are sleeping.
4. 12 VDC power supply (also available below from Amazon)
5. TP-LINK Amazon/Google enables smart switch (linked below from Amazon)
6. Solenoid (linked below from Amazon)
7. 3" Door hinge (linked below from Amazon)
8. Delay Circuit (linked below from Amazon)
9. Misc wire and sheet-metal hardware (from scraps in my workshop)
