This repository is a collection of mini IoT and embedded system projects built during a 15-day hands-on IoT Workshop at my college. Each project demonstrates the integration of sensors, actuators, microcontrollers, and IoT platforms.
These beginner-to-intermediate projects were developed using Arduino Nano and NodeMCU (ESP8266), covering both offline hardware logic and cloud-based IoT control.
| Project Name | Description |
|---|---|
| 🌀 Temperature Controlled Fan | Fan speed control using DHT11 sensor temperature values. |
| 🌡️ Temp & Humidity on LCD | Real-time display of DHT11 temperature and humidity on 16x2 LCD. |
| 🚶 Visitor Counter with Buzzer | IR sensor-based counter with display and buzzer alert. |
| 📦 IR Object Detection | Simple object detection using IR module and LED indicator. |
| 🤖 Line Following Robot | IR sensor-based bot that follows a predefined black line. |
| 💡 Smart Street Light | Auto light control using LDR and IR sensor based on ambient light and motion. |
| 🏠 IoT Smart Home (Blynk) | Remotely control lights/appliances using Blynk mobile app. |
| 🚗 IoT Robo Car (Blynk) | Robot car controlled via smartphone over WiFi using Blynk. |
| ☁️ Sensor Data to ThingSpeak | Upload and visualize DHT11 sensor data on the cloud (ThingSpeak). |
