Creepy Noise Program Using The ESP32

fun prank project using the ESP32 — a creepy beeper that beeps at random intervals and enters deep sleep between beeps to save power and avoid suspicion.

---

🎯 Features of Your Creepy Noise Program:

• Produces a short beep using a buzzer.

• Beeps at random intervals between 1 and 15 minutes.

• After beeping, it goes into deep sleep.

• Wakes up after a random interval and repeats.

---

🧾 Wiring Assumptions:

• Buzzer connected to GPIO 13 (you can change this).

• Buzzer is active high (set HIGH to beep).

 

#include <esp_sleep.h>

#define BUZZER_PIN 13  // Change as needed

void setup() {

  Serial.begin(115200);

  // Initialize buzzer pin

  pinMode(BUZZER_PIN, OUTPUT);

  digitalWrite(BUZZER_PIN, LOW);

  // Beep logic

  beep();

  // Pick a random time between 1 and 15 minutes (in seconds)

  uint32_t minSeconds = 60;      // 1 minute

  uint32_t maxSeconds = 900;     // 15 minutes

  uint32_t sleepTime = random(minSeconds, maxSeconds + 1);

  Serial.print("Sleeping for ");

  Serial.print(sleepTime);

  Serial.println(" seconds...");

  // Convert seconds to microseconds for esp_sleep

  esp_sleep_enable_timer_wakeup(sleepTime * 1000000ULL);

  esp_deep_sleep_start();

}

void loop() {

  // Not used, ESP will deep sleep after setup

}

void beep() {

  Serial.println("Beep!");

  digitalWrite(BUZZER_PIN, HIGH);

  delay(200);  // 200ms beep

  digitalWrite(BUZZER_PIN, LOW);

}
