change the code below and it will work fine
int sensor_pin = 5;
int tap_servo_pin =4;

My sensor is working properly and I copied your code and posted it correctly but my motor is not functioning properly.the motors are moving but not accordingly to sensor .
Please tell me what's the problem.

i need your help on this project
Poornesh said…
first give the correct code for your project mind it
Poornesh said…
you bloody fool first give correct code
Krishna Kumar said…
Bro the given code is not correct the correct code is
#include

const int soilMoisturePin = A0;
const int servoPin = 9; // Adjust these pin numbers according to your setup
const int servo2Pin = 10; // Second servo pin
const int moistureThreshold = 500; // Adjust this value according to your sensor's readings

Servo bridgeServo;
Servo bridgeServo2;

// Define angles for lifted and lowered positions
const int liftedAngle = 90;
const int loweredAngle = 0;

void setup() {
pinMode(soilMoisturePin, INPUT);
bridgeServo.attach(servoPin);
bridgeServo2.attach(servo2Pin);
}

void loop() {
int moistureLevel = analogRead(soilMoisturePin);

if (moistureLevel < moistureThreshold) {
// If soil is moist enough, lift the bridge
liftBridge();
} else {
// Otherwise, keep the bridge down
lowerBridge();
}
}

void liftBridge() {
// Move the servo motors to lift the bridge
bridgeServo.write(liftedAngle); // Use lifted angle
bridgeServo2.write(liftedAngle); // Second servo angle
delay(1500); // Adjust delay as needed
}

void lowerBridge() {
// Move the servo motors to lower the bridge
bridgeServo.write(loweredAngle); // Use lowered angle
bridgeServo2.write(loweredAngle); // Second servo angle
delay(1500); // Adjust delay as needed
}



You should change the signal pin number to 9 and 10
