this is cool code for cat

Thanks

What calls the "loop" function?

hi there, where we can find the wiring diagrams?

Just right here: https://drive.google.com/file/d/1Cpha5PhCjpp5cCY0KYCAVa4Q21_bhWO_/view

How many times a day does this feed. How do i adjust how much food is delivered. Do i just have to play around with the numbers?

Idk what im doing wrong but its a continous loop for me. I would like to stop it after accessing the button but it does not stop. Can anyone help me please?

1. One button pin should be connected to the ground (ground, not 5V), another one to the button pin.
2. ensure you have digitalWrite(buttonPin, HIGH); in your setup to activate internal pull-up resistor
3. show your code please
4. show your wiring

Nice implement. I am confused how it is working though. You first have your servo rotate 30 deg, then wait 575 ms and then rotate 180. Why does it rotate in the opposite direction? Wouldn't the servo go on rotating in the same direction? Thanks.

This code is not for continuous but for a typical servo. So 30 means rotate to 30 degrees and 180 is rotate to 180 degrees. If you use continuous servo 30 (or 0) means rotate counter-clockwise, 90 means stand still, 180 means rotate clockwise.

Got it. Thanks for explaining! Love your cat:)

1.is arduino uno is the same as urs?
2.Is there a different between 180 degree and 360 degree 996 servo motor. Imean which one do i need to buy?
3.how do i make it feed my cat every 1 hour?

You can use any board with PWM

2.Is there a different between 180 degree and 360 degree 996 servo motor. Imean which one do i need to buy?

360 is better

3.how do i make it feed my cat every 1 hour?

You program it. It's not that hard and is a great skill to have.
