The code is:
#define pingTrig 6 #define pingEcho 7 #include Servo myservo; void setup() { pinMode(pingTrig, OUTPUT); pinMode(pingEcho, INPUT); myservo.attach(9); } void loop() { long duration, inches, cm; digitalWrite(pingTrig, LOW); delayMicroseconds(2); digitalWrite(pingTrig, HIGH); delayMicroseconds(10); digitalWrite(pingTrig, LOW); duration = pulseIn(pingEcho, HIGH); cm = duration / 29 / 2; if(cm < 10 ){ myservo.write(90); delay(100); }else{ myservo.write(0); } delay(2000); }

I have and arduino code that make a servo motor turns 90 degrees and go back tô zero when activated by the ultrasonic sensor. (Automatic trash can that open and closes) And it is working fine.
I want tô modify the code tô make it work with a Stepper motor and tb6560.
**the job can be done en less than 10 minutes, Because i will send the code and u just have to make and add a simple modification.
