Accomplishment this week:
1. Design of mechanical system
For the mechanical flipper, M1 needs to have high power to flip the shaft and motor, M2 need to be very light weighted to make the flipping easier for M1. M3 needs to be small to fit between M1 and the music book.
2. Choose stepper motor driver
I found a couple options for the stepper motor driver compatible for Raspberry Pi, but most of them can only get up to two stepper motors (2 Stepper Motor example). Only the driver from Adafruit are stackable that it can run more than two stepper motors.
3. Ordered parts
Adafruit Stackable Motor Driver
Raspberry Pi Extra Tall Stacking Header
4. Picked up parts rom ECE hub
EDE 134: Raspberry Pi 3 Model B+
EDE 150: Stepper Motor
Progress on schedule：
Design mechanical system: On schedule
Control stepper motor with Raspberry Pi: delayed due to part shipment delay
Deliverables hope to accomplish next week:
CAD shafts and flipper
Order M2
Receive M3
