For the last couple of day I've been trying and failed many times just to not use the delay() funtion in Arduino. I have to admitted that my coding skill are extremely bad.
What i trying to do is:
If button is pressed:
Motor A and B move for 1 second at slow speed == > Motor A keep moving but at fast speed and motor B stop.
else:
Motor A and B both stop.
I managed to wrote the code by using delay function for that 1 second. However i got no idea how to do it WITHOUT DELAY() there will be sensor reading as well at the same time, i cant afford that 1 second delay of sensor reading).
Here is my code:
int dir1PinA = 2;
int dir2PinA = 3;
int speedPinA = 9; // Needs to be a PWM pin to be able to control motor speed
// Motor 2
int dir1PinB = 4;
int dir2PinB = 5;
int speedPinB = 10; // Needs to be a PWM pin to be able to control motor speed
int button = 6;
void setup() { // Setup runs once per reset
// initialize serial communication @ 9600 baud:
Serial.begin(9600);
//Define L298N Dual H-Bridge Motor Controller Pins
pinMode(dir1PinA,OUTPUT);
pinMode(dir2PinA,OUTPUT);
pinMode(speedPinA,OUTPUT);
pinMode(dir1PinB,OUTPUT);
pinMode(dir2PinB,OUTPUT);
pinMode(speedPinB,OUTPUT);
// Define button pin
pinMode(button,INPUT);
}
void loop() {
if( button == LOW){ // if button is pressed
// Motor A (move slow) and B moving
analogWrite(speedPinA, 100);//Sets speed variable via PWM
digitalWrite(dir1PinA, LOW);
digitalWrite(dir2PinA, HIGH);
analogWrite(speedPinB, 255);
digitalWrite(dir1PinB, LOW);
digitalWrite(dir2PinB, HIGH);
delay(1000);
// After 1 second Motr A (move fast)and B stop every time button pressed
analogWrite(speedPinA, 255);//Sets speed variable via PWM
digitalWrite(dir1PinA, LOW);
digitalWrite(dir2PinA, HIGH);
analogWrite(speedPinB, 0);
digitalWrite(dir1PinB, LOW);
digitalWrite(dir2PinB, LOW);
}
esle
{
// Both motor not moving
analogWrite(speedPinA, 0);//Sets speed variable via PWM
digitalWrite(dir1PinA, LOW);
digitalWrite(dir2PinA, LOW);
analogWrite(speedPinB, 0);
digitalWrite(dir1PinB, LOW);
digitalWrite(dir2PinB, LOW);
}
}
Please point me out the direction or give me an example of code. And I have already try the Blinkwithoutdelay Arduino example but it does not work for this case.
Very much appreciated.
