MQTT

🚀 IoT Project: Distance Sensor & LED Wave Effect with MQTT 🌟 In this video, we dive into an exciting IoT project using an Arduino and MQTT! 🌐💡 🔧 What You'll See: Distance Measurement: We use an ultrasonic sensor to measure distances and send data via MQTT. Message Handling: When the distance falls within a specified range, a message is published to an MQTT topic. LED Wave Effect: On the receiving end, an LED performs a wave effect based on the received message. 💡 Key Features: WiFi Connectivity: Connects to a WiFi network to publish/subscribe to MQTT messages. MQTT Protocol: Sends and receives messages to/from an MQTT broker. Real-Time Response: Activates an LED wave effect when a specific message is received. 👉 Code Highlights: Sensor Triggering: Accurate distance measurement with the ultrasonic sensor. MQTT Integration: Reliable message sending and receiving. LED Control: Creates a visually appealing wave effect based on incoming messages.
