Day 1 - LemonPad: Today I created the schematic which consisted of 4 switches, the microcontroller (xiao), a rotary encoder, and OLED Screen. Then I created a layout that is compact and should be able to fit all the parts. This all took about 4 hours as I was trying to understand what parts connect to which pin on the microcontroller. Finally the last two hours were trying to learn how to do CAD modeling.
