Moteur pas à pas 4 phases 5 fils en courant continu 5V 28YBJ-48 avec carte de commande ULN2003

Tried this with an Arduino Uno using the MotorKnob example sketch http://arduino.cc/en/Tutorial/MotorKnob Works fine and the 64:1 gearbox gives fairly high output torque. I found by experiment that the connection to Arduino is not obvious: Arduino pin 8 to in 1 (motor blue wire), pin 9 to in3 (motor yellow), pin 10 to in 2 (motor pink), pin 11 to in 4 (motor orange). My first attempt connecting the wires in sequence (8 to in1, 9 to in2 etc) resulted in the motor only turning in one direction! The motor draws about 250 mA at 5V so best to use a separate supply, remember to connect the 0V to one of the Arduino GND pins.
Very good Nagyon jó
Instead of swapping connections around as suggested by other reviewers, I kept the connections in order and edited the sketch. I am using digital outputs D5 to D8 so used this pin assignment: #define motorPin1 5 #define motorPin2 7 #define motorPin3 6 #define motorPin4 8 I find the motor works at 15 RPM but does not work at 20 RPM; this is to be expected for a stepper motor. Torque is surprisingly good. It is not clear what the jumper adjacent to the +5V header pin is for.
Bien emballé et est arrivé dans le temps annoncé. Les tableaux de commande du moteur sont emballés individuellement dans des sacs en plastique résistant à l'électricité statique, ce qui est une belle touche. Tout semble être exactement comme décrit. J'ai hâte de les installer sur le projet. Je recommanderais.
Bem emballé, répond aux attentes. Livraison internationale rapide.
Llego dentro del plazo estimado, en perfectas condiciones, sin aparentes golpes en los productos. Todo en orden.
pas tester encore mais bon materiel !!
bien
Excellent motor & controller for the price
Worked great for me on the arduino. After I used the AccelStepper Lib. (much better timing and more efficient control than the standard lib). Caveat: Only worked when I initialized the AccelStepper lib with Pin 2 and 3 swapped and Half Step Mode: AccelStepper stepper(AccelStepper::HALF4WIRE, motorPin1, motorPin3, motorPin2, motorPin4);
