Hi Everyone,
I need help to get the right code to make the robot work properly. have used below code but is not working. what should I delete or add to below code?
/*------ Arduino Fire Fighting Robot Code----- */
#include <Servo.h>
Servo myservo;
int pos = 0;
boolean fire = false;
/*-------defining Inputs------*/
#define Left_S 9 // left sensor
#define Right_S 10 // right sensor
#define Forward_S 8 //forward sensor
/*-------defining Outputs------*/
#define LM1 2 // left motor
#define LM2 3 // left motor
#define RM1 4 // right motor
#define RM2 5 // right motor
#define pump 6
void setup()
{
pinMode(Left_S, INPUT);
pinMode(Right_S, INPUT);
pinMode(Forward_S, INPUT);
pinMode(LM1, OUTPUT);
pinMode(LM2, OUTPUT);
pinMode(RM1, OUTPUT);
pinMode(RM2, OUTPUT);
pinMode(pump, OUTPUT);
myservo.attach(11);
myservo.write(90);
}
void put_off_fire()
{
delay (500);
digitalWrite(LM1, HIGH);
digitalWrite(LM2, HIGH);
digitalWrite(RM1, HIGH);
digitalWrite(RM2, HIGH);
digitalWrite(pump, HIGH); delay(500);
for (pos = 50; pos <= 130; pos += 1) {
myservo.write(pos);
delay(10);
}
for (pos = 130; pos >= 50; pos -= 1) {
myservo.write(pos);
delay(10);
}
digitalWrite(pump,LOW);
myservo.write(90);
fire=false;
}
void loop()
{
myservo.write(90); //Sweep_Servo();
if (digitalRead(Left_S) ==1 && digitalRead(Right_S)==1 && digitalRead(Forward_S) ==1) //If Fire not detected all sensors are zero
{
//Do not move the robot
digitalWrite(LM1, HIGH);
digitalWrite(LM2, HIGH);
digitalWrite(RM1, HIGH);
digitalWrite(RM2, HIGH);
}
else if (digitalRead(Forward_S) ==0) //If Fire is straight ahead
{
//Move the robot forward
digitalWrite(LM1, HIGH);
digitalWrite(LM2, LOW);
digitalWrite(RM1, HIGH);
digitalWrite(RM2, LOW);
fire = true;
}
else if (digitalRead(Left_S) ==0) //If Fire is to the left
{
//Move the robot left
digitalWrite(LM1, HIGH);
digitalWrite(LM2, LOW);
digitalWrite(RM1, HIGH);
digitalWrite(RM2, HIGH);
}
else if (digitalRead(Right_S) ==0) //If Fire is to the right
{
//Move the robot right
digitalWrite(LM1, HIGH);
digitalWrite(LM2, HIGH);
digitalWrite(RM1, HIGH);
digitalWrite(RM2, LOW);
}
delay(300); //Slow down the speed of robot
while (fire == true)
{
put_off_fire();
}
}
I am not using water pump ...only wants the robot to follow fire when sensor detects fire please anybody can help the project is due this Monday 30th
