DVD drive stepper motor, ULN2003 driver and Arduino
Playing with a DVD drive stepper and an Arduino today. I mostly used the information from here
I omitted the Zener, from the circuit shown. And I’m driving stepper with a cut down version of his code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 | const int motorPin1 =8;const int motorPin2 =9;const int motorPin3 =10;const int motorPin4 =11;void setup() { // initialize the digital pin as an output. // Pin 13 has an LED connected on most Arduino boards: pinMode(motorPin1, OUTPUT); pinMode(motorPin2, OUTPUT); pinMode(motorPin3, OUTPUT); pinMode(motorPin4, OUTPUT); }void loop() { // HALF STEP int motorDelay=10; digitalWrite(motorPin1, HIGH); digitalWrite(motorPin2, LOW); digitalWrite(motorPin3, HIGH); digitalWrite(motorPin4, LOW); delay(motorDelay); digitalWrite(motorPin1, HIGH); digitalWrite(motorPin2, LOW); digitalWrite(motorPin3, HIGH); digitalWrite(motorPin4, HIGH); delay(motorDelay); digitalWrite(motorPin1, HIGH); digitalWrite(motorPin2, LOW); digitalWrite(motorPin3, LOW); digitalWrite(motorPin4, HIGH); delay(motorDelay); digitalWrite(motorPin1, HIGH); digitalWrite(motorPin2, HIGH); digitalWrite(motorPin3, LOW); digitalWrite(motorPin4, HIGH); delay(motorDelay); digitalWrite(motorPin1, LOW); digitalWrite(motorPin2, HIGH); digitalWrite(motorPin3, LOW); digitalWrite(motorPin4, HIGH); delay(motorDelay); digitalWrite(motorPin1, LOW); digitalWrite(motorPin2, HIGH); digitalWrite(motorPin3, HIGH); digitalWrite(motorPin4, HIGH); delay(motorDelay); digitalWrite(motorPin1, LOW); digitalWrite(motorPin2, HIGH); digitalWrite(motorPin3, HIGH); digitalWrite(motorPin4, LOW); delay(motorDelay); digitalWrite(motorPin1, HIGH); digitalWrite(motorPin2, HIGH); digitalWrite(motorPin3, HIGH); digitalWrite(motorPin4, LOW); delay(motorDelay); } |

[…] steppers are controlled by an Arduino using a ULN2003. The steppers seem to be at their limit and I don’t think they could push around much more […]
The guide of playing with a DVD drive stepper and an Arduino does helpful to me..
I would like to close a door with a bolt and this engine would be ideal.
already got 3 recycled.
would you mind sending me the schematics of this engine?
to rotate it in one direction and the other?
Thats it. You are officially my hero of the day! This is just what I was looking for.
hey,
i would like to know the steps per revolution of this DVD stepper motor.
