the code i uploaded to mys arduino just:
#include <AFMotor.h>
AF_DCMotor motor(2, MOTOR12_64KHZ); // create motor #2, 64KHz pwm
void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps
Serial.println("Motor test!");
motor.setSpeed(200); // set the speed to 200/255
}
void loop() {
Serial.print("tick");
motor.run(FORWARD); // turn it on going forward
delay(1000);
Serial.print("tock");
motor.run(BACKWARD); // the other way
delay(1000);
Serial.print("tack");
motor.run(RELEASE); // stopped
delay(1000);
}
after my uploaded code success i tyr to connect motorDC to M2 but it is not work
and if i try to connect motor dc to M4 and gnd this motor is works but that motor works like nothing have command from this code
