Circuit Delay Timer

Hello,

I’m extremely new to electronics and trying to build a toy for my cat to periodically release pingpong balls while I’m away at work. I recently made the demo circuit shown below, and I am trying to add a delay timer so the servo will run for a set (but adjustable) time range (0.25 - 5 second servo operating time), then turn the servo off for a set (but adjustable) time range (1-30 minute servo “off” time).

Here is the link to the demo circuit I assembled (The “Getting Started Quickly” circuit):

As mentioned, I’m brand new to electronics as a hobby and I am trying to avoid coding for this initial project as I get my feet wet. I purchased the SparkFun Nano Power Timer ( https://www.sparkfun.com/products/15353 ), but (a) I am not sure if that is right part for my intended application, and (b) if it is the right part, I am not sure how to insert the nano power timer into the completed circuit referenced above.

Does anyone have any recommendations for additional parts/circuit build guides that I could purchase/reference to complete the remainder of this project without coding?

Thank you!

Use a 555 timer. Look for a circuit with interdependently adjustable on/off times. Search images on google – an astable circuit is what you need. a couple capacitors and trim pots and that’s it.
