#arduino-stepper
Camera stand that can rotate and turn up and down to capture and identify objects anywhere in the room, through AI/ML software.
Handcrafted from plywood, with dense wood to connect to the motor axis. Rotor diameter is 20cm, height is approx. 16cm.
Two 4-wire stepper motors, connect to Arduno Uno via pins 2-5 (a1-4) and 6-9 (b1-4) through ULN2003 drivers. Arduino is bus powered, motors use external 5V power supply. With the built in gear the motor requires 512 full steps for a 360° turn.
Load serial4stepper.ino into the Arduino. It should appear as /dev/ttyACM0. Use arduino-serial.py to send commands, one per line:
- l - left
- r - right
- u - up
- d- down
- (number) - sets the step size for all following operations
- rot - returns the hardware counter for rotation
- ele - returns the hardware counter for elevation
- reset - resets the hardware counters and returns "OK"
CAD layout and 3d-printed stand with better bearings and less play, cabling that allows 360° turns.
