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   uin...
