Aduino Stepper Motor Acceleration and Rotary Encoder Control
Old days Harddisk
This harddisk was made in 1988 and has a capacity of 20MB, you may just store a few pictures today.
This harddisk has a step motor to drive the heads which in modern HDs have electromagnetic coil magnet driver.
I like very much these kind of piece of art.
Happy New Year
