IOT lesson 8- Bluetooth connections

In lesson eight i learnt about the three major Bluetooth connections of the arduino board.

1. Bluetooth Classic (Serial): Enables Arduino devices to wirelessly communicate with smartphones, tablets, and computers using Bluetooth serial communication protocols, facilitating short-distance data transmission.

2. Bluetooth Low Energy (BLE): Designed for low-data-rate applications, BLE allows Arduino boards to communicate with BLE-enabled devices like smartphones and sensors, offering power-efficient wireless connectivity and longer battery life.

3. Bluetooth Mesh: Facilitates decentralized IoT systems by enabling Arduino devices to create large-scale wireless communication networks, allowing multiple devices to communicate without a centralized hub, suitable for smart home automation, industrial applications, and environmental monitoring.
