Meet Aditya Krishna, an S7 Electronics and Communication Engineering student from Amritapuri Campus, presents his innovative mini-project on IoT-based secure communication using the ESP-NOW protocol. His project, “ESP-NOW Communication Protocol for IoT Sensor Networks,” explores how two ESP32 microcontroller boards can exchange data effectively without the need for Wi-Fi or Bluetooth, creating a secure, connectionless communication link. This technique enables one-to-one, one-to-many, and broadc
