Learn to build a pressure pad lap counter using ESP32 and Node-RED in this 38-minute tutorial. Inspired by Captain Tom Moore's NHS fundraising efforts, create an interactive system that counts laps and updates a dashboard display. Explore hardware setup with an ESP32 and pressure mat sensor, program the ESP32 to send MQTT messages, and develop a Node-RED flow for dashboard updates and sound effects. Gain practical skills in IoT development, sensor integration, and real-time data visualization applicable to escape room puzzles and interactive projects.
