Using an atmel microprocessor (attiny2313) to make a "simon says" game for my dog (yep, for a treat). I have all the game play programmed and starting to look at the hardware required to accomplish this. The game play is through 4 large buttons which I have successfully torn down and interfaced with my microprocessor (if you're curious, it's these: https://www.amazon.com/gp/product/B00B2FNHB6/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1)
The only thing left is to open and close the treat "hatch". What I'm thinking of is probably a 4"x4" sliding door type hatch. The open/close is controlled by the microprocessor.
I haven't done any stepper motor or servo motor controls yet, so I'm looking for ideas on how to accomplish this. I think I could use a servo with a longer arm which pulls and pushes this sliding hatch, but I'm wondering if a stepper would be a better way to go?
