Arduino sketch examples:
Simple test to drive a 4-phase stepper motor using simple Move() and AccelMove() functions.
Simple test to drive a single 4-phase stepper motor using the small but mighty 8-pin ATtiny85 microprocessor.
Laser Gimbal with 2 Stepper Motors based on Thingiverse project: https://www.thingiverse.com/thing:4561012
Test cycles each stepper then draws a circle with the laser pointer. Switches allow users to move the center of the circle (up/down/left/right).
- Arduino Microcontroller (e.g. Uno)
- 2 x 28BYJ-48 Stepper Motors
- 2 x ULN2003 Driver Board
- 1 x Laser (e.g. 5V 650nm 5mW Red Dot Diode Laser)
- 4 x Microswitches
- 4 x 61k Ohm Resistors (pull up resistor for switches)
- 5V Power Supply (do not power steppers with Arduino)
Robotic Arm with 3 Stepper Motors based on Thingiverse project: https://www.thingiverse.com/thing:2838859
Test cycles each stepper and then responds to user switches (up/down) for stepper motion.
- Arduino Microcontroller (e.g. Mega2560)
- 3 x 28BYJ-48 Stepper Motors
- 3 x ULN2003 Driver Board
- 6 x Microswitches
- 6 x 61k Ohm Resistors (pull up resistor for switches)
- 5V Power Supply (do not power steppers with Arduino)
