Turntable, with a 28BYJ-48 5-wire unipolar stepper motor
thingiverse
Construction of a turntable, with a 28BYJ-48 5-wire unipolar stepper motor. Turntables have long been used in shop windows as display stands, especially in watch and jewelry stores. In my case, I am going to use it to record some scenes of electronic montages. This turntable can rotate in both directions with great precision, and at a configurable speed to choose from one of its 6 presets. The motor controller is made with an Atmega328P (Arduino) microcontroller. Taking advantage of the high turning precision of stepper motors, this turntable could be used as a cyclical timer, mounting cams on the plate to operate one or more pushbuttons.
