Today I have worked on prototyping for electronics, I followed guides from small makers and loosely followed a schematic that uses an arduino uno. i am using esp32 so this is different. I drew out a schematic laying out features that I want. I also decided that I would want a remote for changing face expressions rather than a button somewhere on the head. I want to add a boop sensor using infrared and a mic using MAX9814. Lastly I add a SSD display to show the modes I am on. the matrix are wired up in a chain it seems. my research includes finding which components people use to add and I want to add my own spin to it. To make it unique rather than a bland protogen.
