(HD) Auto-Connect BT to BT Module Without Using Arduino At All – Presence Detection System

This video demonstrates the “Presence Detection System” concept. This project uses a pair of Bluetooth modules which is HC-05 (master) and HC-06 (slave), a USB to UART converter to connect the BT modules to the computer and a relay module for building up application circuit. The BT modules need to be set up with certain […]
