Code is not opening can you resend it

code const int trigPin = 3; const int echoPin = 2; const int buzzer = 5; long duration; int distance; int safetyDistance; // Adjust this value to change the speed of sound for your environment const float speedOfSound = 0.0343; // 343 meters per second (default) void setup() { pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); pinMode(buzzer, OUTPUT); Serial.begin(9600); } void loop() { digitalWrite(trigPin, LOW); delayMicroseconds(2); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); duration = pulseIn(echoPin, HIGH); // Calculate distance using the adjusted speed of sound value distance = (duration * speedOfSound) / 2; safetyDistance = distance; if (safetyDistance <= 30) { digitalWrite(buzzer, HIGH); } else { digitalWrite(buzzer, LOW); } Serial.print("Distance: "); Serial.println(distance); }

I didinit get the link

Bro the code was not opening

Baiya help me please code download nahi ho raha hai aur mere project ko 3 din hi bache hai help me please

Please circute diagram

Bro can i know why battery s negative is connected to transistor s collector.

how do i extend the wire from the button to nano

What is the purpose of this project

Where to put or add buzzer?.. also power source

Can u pls share code and also what was power source

Amazing

What is the code and how to use it?

Project not working even i upload code and all circuit checked, sensor is deceting nothing i tryed 2 sensors which are new even tryed with current of pc and battery ,pls help i am a student i dont want to my money be wasted 😭😭

Code is saying error

const int trigPin = 9; const int echoPin = 10; const int buzzer = 12; void setup() { pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); pinMode(buzzer, OUTPUT); Serial.begin(9600); } void loop() { long duration, distance; // Send a pulse to measure distance digitalWrite(trigPin, LOW); delayMicroseconds(2); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); // Measure distance duration = pulseIn(echoPin, HIGH); distance = duration * 0.034 / 2; // Convert to cm // If object is close, trigger the buzzer if (distance > 0 && distance < 50) { digitalWrite(buzzer, HIGH); delay(100); // Sound for 100 ms digitalWrite(buzzer, LOW); delay(100); // Pause for 100 ms } else { digitalWrite(buzzer, LOW); } delay(200); // Adjust the delay to avoid excessive feedback }

What type of cable are you using? Is it male-male / female-male / male-female? Please answer, I really need it 🙏

how to upload code?

😮
