README.md StepperDriver A4988, DRV8825, DRV8834, DRV8880 and generic two-pin stepper motor driver library. Features:. Constant speed mode (low rpms).

1. Arduino Stepper Library Functions

Stepper One Revolution: Turn the shaft one revolution clockwise and one counterclockwise. Stepper One Step At A Time: Turn the shaft step by step to check the proper wiring of the motor. Stepper Speed Control: Control the stepping speed with a potentiometer. Stepper Library for Arduino This library allows you to control unipolar or bipolar stepper motors. To use it you will need a stepper motor, and the appropriate hardware to control it.

Linear (accelerated) speed mode, with separate acceleration and deceleration settings. Non-blocking mode (yields back to caller after each pulse). Early brake / increase runtime in non-blocking mode Hardware currently supported:. Low-Voltage Stepper Motor Driver up to 1:32. Stepper Motor Driver up to 1:16. up to 1:32.

up to 1:16, with current/torque control. any other 2-pin stepper via DIR and STEP pins, microstepping up to 1:128 externally set Motors 4-wire bipolar stepper motor or some 6-wire unipolar in 4-wire configuration (leaving centers out). Connections Minimal configuration from: Wiring This is suggested wiring for running the examples unmodified. All the pins below can be changed. Arduino to driver board:. DIR - D8. STEP - D9.

SLEEP - HIGH (Vdd). GND - Arduino GND. GND - Motor power GND. VMOT - Motor power (check driver-specific voltage range). A4988/DRV8825 microstep control. MS1/MODE0 - D10.

MS2/MODE1 - D11. MS3/MODE2 - D12. DRV8834/DRV8880 microstep control. M0 - D10. M1 - D11.

ENABLE (optional) recommend D13 to see when coils are active. driver board to motor (this varies from motor to motor, check motor coils schematic). 100uF capacitor between GND - VMOT.

Make sure to set the max current on the driver board to the motor limit (see below). Have a motor power supply that can deliver that current.

Make sure the motor power supply voltage is within the range supported by the driver board. Set Max Current The max current is set via the potentiometer on board. Turn it while measuring voltage at the passthrough next to it. The formula is V = I 5R where I=max current, R=current sense resistor installed onboard. DRV8834 Pololu board, R=0.1 and V = 0.5. max current(A).

For example, for 1A you will set it to 0.5V. DRV8825 low-current board, R=0.33 and V = 1.65.

max current(A). For example, for 0.5A the reference voltage should be 0.82V For latest info, see the Pololu board information pages. Code See the BasicStepperDriver example for a generic driver that should work with any board supporting the DIR/STEP indexing mode. The Microstepping example works with a DRV8834 board. For example, to show what is possible, here is the ClockStepper example that moves a stepper motor like the seconds hand of a watch.
