Bonjour, je suis français aussi... C'était juste une histoire de tension trop faible 4,8V (un peu comme sur Raspberry), j'ai augmenté ma tension à 5,5V et tout est ok.J'ai décuplé le système avec toujours un Atmel 328p chinois mais 2 moteurs pour motoriser l'ensemble:#include <Stepper.h>const int stepsPerRevolution1 = 64;const int stepsPerRevolution2 = 64;const int buttonA = 2;const int buttonB = 3;const int buttonC = 4;const int buttonD = 5;Stepper myStepper1(stepsPerRevolution1, 6, 7, 8, 9);Stepper myStepper2(stepsPerRevolution2, 10, 11, 12, 13);void setup() { pinMode(buttonA, INPUT); pinMode(buttonB, INPUT); pinMode(buttonC, INPUT); pinMode(buttonD, INPUT); myStepper1.setSpeed(100); myStepper2.setSpeed(100); Serial.begin(9600);}void loop() { while(digitalRead(buttonA) =...

Hi, it's my first stepper use, and it's not working... I've the same parts (motor, board, etc), the same .ino file, and button 2 is working well (clockwise turning), but not the button 1 (motor make sound but don't turn), may have you an idea ?

For the new versionA 1264 with blue board 820-2407-A and only with 6 black wires:There is no 5 V, 3 wires for GND and 3 for the 3.3 v BUT they are inverted, see the picture !

Thanks, it's a polystyrene glass, cheap and easy to work.
