GDG on Campus Rajalakshmi Engineering College - Chennai, India

As part of the cutting-edge technology initiative, GDG OnCampus REC successfully hosted an interactive workshop focused on Internet of Things (IoT), introducing participants to the exciting world of connected devices and smart solutions. Led by IoT experts Deepesh O (IoT Lead, GDG REC) and Mohit O (IoT Associate, GDG REC), this hands-on event brought together students from all years for practical learning, collaboration, and engaging IoT project development using industry-standard simulation tools like Tinkercad Circuits and Wokwi.

Workshop Objectives

The primary goal of this workshop was to demystify IoT technology and equip students with foundational knowledge and practical skills to build their first IoT projects. Participants gained hands-on experience with microcontroller programming, sensor integration, and circuit simulation, fostering understanding of how interconnected devices communicate and solve real-world problems through virtual prototyping.

Structure of the Workshop:
1. Introduction to IoT Fundamentals The workshop began with an overview of Internet of Things concepts, exploring how physical devices embedded with sensors, processing capabilities, and network connectivity create smart solutions. Participants understood the significance of IoT in modern technology landscapes and its applications across industries from smart homes to industrial automation.

2. Getting Started with IoT Starter Pack Students received detailed guidance on essential IoT components that form the foundation of any connected device project.
The session covered:
● Microcontrollers: Understanding Arduino and ESP8266/ESP32 as the "brain" of IoT systems.
● Sensors: Temperature, humidity, motion, and environmental sensors for data collection.
● Actuators: LEDs, motors, and relays for controlling physical devices.
● Connectivity: WiFi modules and communication protocols for internet connectivity.

3. Hands-On Experience with Tinkercad Circuits Students received step-by-step guidance on using Tinkercad Circuits, Autodesk's free online simulation platform for IoT prototyping. This included circuit design, component placement, virtual wiring, and testing IoT systems without requiring physical hardware, making learning accessible and cost-effective for all participants.

4. Exploring Wokwi IoT Simulator Participants explored advanced IoT simulation capabilities using Wokwi, learning to create complex IoT scenarios and test various sensor configurations in virtual environments. This session emphasized practical experimentation with different microcontroller boards, sensor combinations, and programming approaches.

5. Building Your First IoT Project The workshop culminated in guided projects where students designed and simulated their own IoT applications, applying concepts learned throughout the session. Participants worked on real-world scenarios including:
● Smart Home Automation: Controlling lights, fans, and appliances remotely
