12-Week Program

Curriculum — C++, IDE & Sensors

Every session is written and run inside the Arduino IDE. You type real C++ code, upload to the board, and see it work — every week.

IDEC++LEDSensorProject
Week 01IDE

Arduino IDE Setup + First C++ Program

void setup() { Serial.begin(9600); }
void loop() { Serial.println("Hello IoT!"); }

Install IDE, upload first sketch to board

Week 02C++

C++ Basics — Variables, loops, if/else

for (int i = 1; i <= 10; i++) {
  Serial.println(i);
  delay(500);
}

Count from 1–10 on Serial Monitor with loops

Week 03LED

Digital Output — LED Blink

digitalWrite(LED_PIN, HIGH);
delay(1000);
digitalWrite(LED_PIN, LOW);
delay(1000);

Blink LED using pinMode() & digitalWrite()

Week 04LED

LED Patterns — Arrays & for-loops

int pins[] = {2,3,4,5};
for (int i = 0; i < 4; i++) {
  digitalWrite(pins[i], HIGH);
  delay(200);
}

Sequence multiple LEDs using C++ arrays

Week 05C++

Digital Input — Push Button + Functions

bool isPressed() {
  return digitalRead(BTN) == LOW;
}

Toggle LED with button; write a C++ function

Week 06Sensor

Analog Input — Potentiometer & map()

int val = analogRead(A0);
int brightness = map(val, 0, 1023, 0, 255);
analogWrite(LED_PIN, brightness);

Read analog value; control LED brightness (PWM)

Week 07Project

Mini Project 1 — LED Dimmer

// Student writes complete sketch
// using all Week 1–6 concepts

Full C++ sketch: pot + LED + Serial output

Week 08Sensor

Temperature Sensor — DHT11 Library

#include <DHT.h>
DHT dht(4, DHT11);
float t = dht.readTemperature();
Serial.println(t);

Read temp & humidity; print formatted data

Week 09Sensor

Ultrasonic Sensor — Distance & Alerts

long duration = pulseIn(ECHO, HIGH);
float cm = duration * 0.034 / 2;
if (cm < 10) digitalWrite(LED, HIGH);

Measure distance; flash LED when object too close

Week 10Sensor

IR Sensor + C++ Switch-Case

switch (state) {
  case 1: blinkFast(); break;
  case 2: blinkSlow(); break;
}

Detect object; run different actions per sensor

Week 11Project

Final Project — Student's Own C++ Sketch

// Student chooses sensors,
// writes all C++ logic,
// comments and uploads

Design + code a sensor project from scratch in IDE

Week 12Project

Demo Day + Certificate

// Present your code &
// explain the logic
// to the batch

Live code walkthrough, Q&A, certificate handout

Rolling 12-week cycle — join any batch. After Week 12, Level 2 (WiFi · Cloud · MQTT) begins.

Frequently Asked Questions

Do I need any prior coding knowledge?

No prior experience needed. We start from scratch — basic Arduino C++ and simple Python snippets. If you can type on a laptop, you can join.

Where do I buy the IoT kit?

We will share a shopping list on Day 1. Kits are available on Amazon, Robu.in, or locally in Nagercoil electronics shops for around ₹600–800 total.

What laptop specification is needed?

Any Windows or Mac laptop made in the last 8 years with a USB port. Minimum 4 GB RAM. We will help you install Arduino IDE and Python (both free) before the first session.

Is there a certificate?

Yes — students who complete all 12 sessions and present their final project receive a QDCODEX IoT Course Completion Certificate.

Can school students (Gr 9–12) and college students be in the same batch?

We run separate batches. School students (Gr 9–12) typically on Saturday mornings; college students on Sunday afternoons. This keeps the pace right for each group.

What happens after completing the 12-week cycle?

Students can join Level 2 (Advanced IoT + Python + MQTT + Home Automation projects) or apply for a QDCODEX internship program to build a real product.
