![]() remember the previous value of the sensor move a number of steps equal to the change in the Stepper myStepper(stepsPerRevolution,12,13) Potiometer wiper to Analog 0, one end of the element to GND, other end to Vin. The values on the potentiometer could be played with to get better motion. Its basically the knob stepper example, but for the R3 motor shield. I was able to get this code to work though. The r3 board, I think, uses different parameters. Wiring sounds correct, without knowing the specs of your motor. the Arduino book I have by Simon Monk arrived and turned out to not have anything about wiring up steppers. If any of you guys see something wrong with the code or the wiring for the motor let me know. Stepper.step(-200) //move 360 deg in the other direction Stepper.step(200) //move 360 deg one direction ![]() Stepper stepper(STEPS, 12, 13) //create the stepper #define STEPS 200 //1.8 deg motor (200 steps per rev) which I can't verify that it works cause the code below sort of moves the motor, the shaft sort of vibrates and when it gets to what i think is wave the flag the motor shaft turns a little: I then plugged in black to A+ and Green to A-, then Red to B+ and Blue to B- I took the white and yellow twisted together and connected to the GND terminal. According to wiring diagram the green and black was one coil and the red and blue was the other, then directions i found stated to have the center taps, in my case white and yellow connected to ground. Im in the same exact boat!!! I have an Arduino uno+R3 motor shield with a nemea 23 stepper but it had 6 wires. set the motor speed (for multiple steps only): set the PWM and brake pins so that the direction pins // can be used to control the motor: Stepper myStepper(stepsPerRevolution, 12,13) initialize the stepper library on the motor shield Incase someone else runs into this problem, this is the code that worked:Ĭonst int stepsPerRevolution = 48 // change this to fit the number of steps per revolution I was completely lost at first, then I found a code of someone that had the same Motor Shield, and it works.
