When raspberry Pi motor controling program ended, motor still work

Question

I am controlling motor with raspberry pi, using wiringPi. I made my code, and implemented. It worked. But when I exit the code, motor was still working. How can I stop this?

while(1){
            digitalWrite(EN1, HIGH);
            digitalWrite(IN1, HIGH);
            digitalWrite(IN2, LOW);
            delay(10000);

            digitalWrite(EN1, LOW);
            delay(5000);

            digitalWrite(EN1, HIGH);
            digitalWrite(IN1, HIGH);
            digitalWrite(IN2, LOW);
            delay(10000);

            digitalWrite(EN1, LOW);
            delay(5000);
    }

do you stop your motors before exiting ? Can you edit your post and put your code ? — David Bensoussan, Jun 14 '16 at 13:08
I didn't. But if I exit, I think ports will be stop to sending 5v or 0v. — Ju-Ae, Jun 15 '16 at 12:56

Because of your

while (1)

I understand you stop with a signal, like Ctrl-C. You should use signal handler to handle the stop and when you catch the signal, you should stop the motors with

digitalWrite(EN1, LOW);

Thank you! And when I use softPwmWrite, I can stop with Ctrl-C even if I use while(1). – Ju-Ae Jun 16 '16 at 06:31
