THE ENTER BUTTON
Description
I designed this enter button as a alternative to a usual keyboards enter button. Printing: The print consists out of three parts: EnterButton1.0, EnterButton1.1 and EnterButton1.2. I printed 1.0 and 1.1 together. Only the 1.1 needs support placed under the 14 mounting holes. The 1.2 I printed seperately. Have a look at the .3mf printing files for more information. Electrical Stuff: The enter button consists of a adafruit Trinket M0 and a hall sensor. Have a look at the given schematic.
