Free Roadmap

Become an IoT & Robotics Engineer from scratch

Make your code move things in the real world. Go from zero electronics to connected devices and a working robot in about five months — the hands-on path into Industry 4.0.

The one rule

Wire it → code it → make it move

Hardware punishes theory-only learning instantly. Build every circuit, flash every sketch, and let things fail — a burnt LED teaches more than a perfect lecture. Free simulators count when parts aren't handy.

Important: A basic Arduino/ESP32 starter kit costs about ₹1,500–2,500 and covers the first three months. Until you have one, Wokwi and Tinkercad simulate almost everything free — never let missing parts stop the learning.

The Roadmap

Four phases, step by step

0

Foundations

Weeks 1–5

Electronics and the first microcontroller.

Week 1

Electricity basics

Voltage, current, resistance, breadboards — safely.

Week 2

Arduino first steps

Digital/analog pins, blink, buttons (Wokwi works too).

Week 3

C/C++ for embedded

Just enough to write clean sketches.

Week 4

Sensors

Temperature, distance, light, motion — read them all.

Week 5

Actuators

LEDs, buzzers, servos, relays — make things happen.

1

IoT

Weeks 6–11

Put your devices on the internet.

Week 6

ESP32 & WiFi

The ₹300 chip that connects anything to the internet.

Week 7

MQTT

The messaging protocol of IoT, hands-on.

Week 8

Cloud dashboards

Stream sensor data to live charts (free tiers).

Week 9

Control from anywhere

Switch devices from your phone, safely.

Week 10

Power & reliability

Batteries, sleep modes, surviving reboots.

Week 11 · Project ▶

Smart-home node

A WiFi sensor + relay node with a live dashboard.

2

Robotics

Weeks 12–17

Motors, vision, and a robot that decides.

Week 12

Motors & drivers

DC motors, H-bridges, PWM speed control.

Week 13

Robot chassis

Build a two-wheel-drive robot base.

Week 14

Raspberry Pi + Python

A Linux brain for bigger robots.

Week 15

Computer vision

OpenCV basics — follow a line or a colored ball.

Week 16

Control loops

Sense → decide → act; simple PID intuition.

Week 17 · Project ▶

Autonomous robot

An obstacle-avoiding or line-following robot.

3

Integration

Weeks 18–22

Robots + cloud + polish = Industry 4.0 portfolio.

Week 18

Robot telemetry

Stream your robot's sensors to your IoT dashboard.

Week 19

ROS 2 taste

The framework real robotics companies use.

Week 20

Mechanics & mounting

3D-printed or hand-built parts that don't fall off.

Week 21

Testing & safety

Fail-safes, e-stops, and honest documentation.

Week 22 · Capstone ▶

Connected robot system

A robot you can monitor and command over the internet.

Build a Portfolio

Five projects that get you hired

Projects beat certificates. Do them in order — each builds on the last. Put every one on GitHub with a clear README.

Start here

1 · Sensor Station

Read three sensors and display live values (Wokwi or real board).

IoT

2 · WiFi Weather Node

An ESP32 that streams temperature to a live cloud dashboard.

Automation

3 · Smart-Home Controller

Control lights/appliances from your phone via MQTT.

In demand

4 · Vision Line-Follower

A robot that follows a track using a camera and OpenCV.

Capstone

5 · Internet-Connected Robot

Drive and monitor your robot from a web dashboard.

Do This Today

Your first step (takes 30 minutes)

1. Open Wokwi

wokwi.com — a free online Arduino/ESP32 simulator. No hardware needed.

2. Blink an LED

The 'hello world' of hardware — in the simulator or on a real board.

3. Read one sensor

Wire (or simulate) a temperature sensor and print its values. Started.
