Welcome to ROY TECH LAB

Igniting Young Minds Through Robotics & Innovation

At ROY TECH LAB, we believe the future belongs to the creators, the innovators, and the problem-solvers. That’s why we bring hands-on robotics education directly to schools — making STEM learning fun, engaging, and practical for students.

🚀 Started in February 2025, our journey began with a vision to empower schoolchildren with real-world tech skills. 🏫 Our first proud collaboration was with Ramkrishna Mission Vivekananda Vidyamandir, Malda and we’re just getting started!

What We Do

School Robotics Programs: We conduct interactive classes that teach students how to build and code their own robots using Arduino, ESP32, sensors, and more.
STEM Learning Made Fun: Through real projects like line-following robots, human-following bots, and smart cars, we help students apply classroom science in exciting ways.
Workshops & Exhibitions: We organize school-level competitions, demo days, and STEM exhibitions to showcase student creations and boost confidence.

Why Choose Us?

✅ Curriculum-Aligned Projects
✅ Beginner-Friendly Approach
✅ Real Hardware – Not Just Theory
✅ Guided by Experts in Robotics & Coding

Laser Alarm Security System

        //here is the code for Laser Alarm Security System
        #define LDR_PIN 2       // Digital pin connected to LDR module OUT pin
#define BUZZER_PIN 8    // Digital pin connected to buzzer or alarm

void setup() {
  pinMode(LDR_PIN, INPUT);
  pinMode(BUZZER_PIN, OUTPUT);
  digitalWrite(BUZZER_PIN, LOW);  // Start with buzzer OFF
  Serial.begin(9600);
  Serial.println("Laser Alarm Ready...");
}

void loop() {
  int ldrValue = digitalRead(LDR_PIN);

  if (ldrValue == HIGH) {
    // Light is detected (laser on LDR) → No alarm
    digitalWrite(BUZZER_PIN, LOW);
    Serial.println("Safe: Light Detected");
  } else {
    // Light is blocked (someone interrupted the laser) → Alarm ON
    digitalWrite(BUZZER_PIN, HIGH);
    Serial.println("⚠ Intrusion Detected!");
  }

  delay(100); // short delay for stability
}
