There is a second version of my schematic and only one version of the software flowchart which are my final versions. Thank you!

Schematic looks good... diodes for voltage protection will need some specification (assuming you want Zener diodes with specified breakdown voltages).

W/r to the software flowchart, I'm not sure what you are referring to with "sub-loops" of the different brightness modes. Insights?

Melhorowitz19 commented 5 years ago

Right now I just have Schottkey diodes in place. I looked it up for a while last night but I'm still a bit confused: is it necessary for Schottkey diodes in that configuration to have the 5 V forward voltage as well? Or would it be better to just have that single 5 V Zener diode across the input (though I had trouble finding a diode with a specific forward voltage last night)?

Also, would it be possible to just attach the ATMega from Arduino directly to the PCB, instead of using header pins to reduce weight?

For the flow-chart, the sub-loops were just to signify that it was staying in that operating mode until it was changed by a button pressed; I already uploaded my code and clarified that a bit more.

Thank you!

I think that a single Zener would be fine.

Yes, you can just attach the chip... that comes with some additional overhead, and I would recommend attaching it with a female socket so that you can easily remove / replace it instead of having to desolder all of those pins!

Code is looking good!
