This is a turntable,
You will need:
- Raspberry pi pico/ pico W
- 28-byj48 Stepper motor
- ULN 2003 stepper driver
- Thonny IDE for flashing firmware the microcontroller (pico)
- 5x M2 screws (1x for the shaft to the motor, 4x for fixing pico)
- 2x M4 screws for the motor to the housing
- Push buttons / momentary switches - AMAZON link
From the files:
The shaft goes on the shaft and is fixed by a 1x M2 screw. raspberry pi goes on the tall screw bosses which are for M2 screws. Motor goes on the shorter screw bosses which are for M4 screws.
For the firmware download this CODE from my GitHub. Flash it via thonny and rename it to main.py when you add it to pico. (you need pico to run the micropython - check YT videos on how to do it.)
Refer to the circuit diagram for connections
(Button 1- green, 2- blue, 3- red)
Refer to this video on how it works.
PS: update to the code is coming where you can change the speed with a double press.
