Hello Everyone,
I'm here asking for help for my project, what I'm facing now is, is don't know how to make my stepper motor stop in a certain direction, Here is what I want my project to work,
When there is no force detected stepper motor should not move,
when there is force detected the stepper motor should spin in a clockwise direction and stop at a certain step until when the force is removed then the stepper motor will spin in a counter-clockwise direction and stop at a certain step.
From now what I manage is, manage to have the force sensor when there is force it will move in a clockwise direction and when the force is removed it will turn counter clock-wise, but it did not stop in a certain direction.
Below is my code.
#define dirPin 5
#define stepPin 2
#define stepsPerRevolution 1600
int fsrAnalogPin = 0;
int fsrReading;
void setup() {
// Declare pins as output:
pinMode(fsrReading, INPUT);
pinMode(stepPin, OUTPUT);
pinMode(dirPin, OUTPUT);
}
void loop() {
Serial.begin(9600);
fsrReading = analogRead(fsrAnalogPin);
Serial.print("Analog reading = ");
Serial.print(fsrReading);
if(fsrReading > 200){
digitalWrite(dirPin, LOW);
// Spin the stepper motor 1 revolution slowly:
for (int i = 0; i < 500; i++) {
// These four lines result in 1 step:
digitalWrite(stepPin, HIGH);
delayMicroseconds(1000);
digitalWrite(stepPin, LOW);
delayMicroseconds(1000);
}
delay(2000);
}
else if(fsrReading < 200){
digitalWrite(dirPin, HIGH);
// Spin the stepper motor 1 revolution quickly:
for (int i = 0; i < 500; i++) {
// These four lines result in 1 step:
digitalWrite(stepPin, HIGH);
delayMicroseconds(1000);
digitalWrite(stepPin, LOW);
delayMicroseconds(1000);
}
delay(2000);
}
}
