IoT Nexus – Learn & Build

Learn the Internet of Things by building real projects. IoT Nexus – Learn & Build gives makers, students and electronics enthusiasts a structured library of 216 guided IoT projects. Begin with simple sensor readings and move toward connected dashboards, automation, low-power nodes, mesh communication and edge-AI concepts. BUILD ACROSS 18 LEARNING TRACKS Explore Smart Home, Agriculture, Environment, Safety, Energy, Health, Transport, Industry, Smart City and educational weather projects. Every track includes beginner, intermediate and advanced builds. EACH PROJECT INCLUDES • A clear project goal and brief explanation • A visual circuit architecture • Required boards, sensors and components • Step-by-step assembly instructions • Starter Arduino-style code • Communication protocol and estimated build time • Practical safety guidance LEARN AT YOUR OWN PACE Search all 216 projects, filter by category or difficulty, save interesting builds and mark completed projects. Move directly to the next project without returning to the library. FROM FIRST SENSOR TO CONNECTED SYSTEM Work with ESP32, ESP8266 and Arduino-based concepts. Learn HTTP, MQTT, ESP-NOW, webhooks, REST, local storage and secure communication patterns through practical project ideas.
