Super Beginner Electronics Project Help
February 6, 2021 - 10:04pm

Hey Circuit Digest,

I am currently gearing up to transfer to a new college where I will be studying electrical engineering (sophomore level), and as such I would like to try a basic electronics project to get my feet wet in the subject.  My family and I have been having coordination issues where sometimes the dogs will be fed twice for a meal.  And while they don't seem to mind, they have been getting larger than usually even with regular exercise.  To solve this problem, I was thinking of using a teensy with an LCD display and then 3D printing a casing for it.  The LCD would display each of the dogs' names and then buttons on the side would register whether either dog has been fed or not.  (One of our dogs HAS to have cat food infused in his food otherwise he will wait to eat.  My dad refuses to indulge in this and as such, this particular dog will wait until someone else prepares his meal.  Because of this, there needs to be two buttons for each dog.)   This will need some sort of internal clock to reset the feed times at an hour before their feeding times.  Ideally, I was hoping this could be battery powered so I could mount it above one of their food bowls.  So with this in mind, I had some questions.  

-What would your thought process be like in designing something like this?  

-Could a configuration as I've described work? 

-How would you determine whether a battery vs. connecting a cord would work better?  

Thanks for all of your help.

Hello professor,

Thats a really good idea.

Irrespective of the questions you have, before answering, I want to ask how would you determine if the dog is fed? I am looking directly on the sense mechanism. Did you have any plan?

Hey Mr. Gupta,

I or someone else in my family would manually feed the dogs, then push the button on the device registering that they had been fed.  Is that what you were looking for?

Thanks,

Professor Sandwich

First I will think input output of the sytem and make a logic diagram or flow chart of the applicaiton. Think about possible microcontroller based on my experience and start to write the codes.

Could a configuration as I've described work? 

Yes.

How would you determine whether a battery vs. connecting a cord would work better? 

I will choose cord as there will be no worries about drainage of the battery and power consumption.

Very interesting indeed...
