8051-UART part3 - Interfacing HC05 Bluetooth & Relay Control
HTML-код
- Опубликовано: 2 июл 2021
- Bluetooth module HC05 can be used as a wireless replacement for duplex serial communication.
This module is 3.3v device , but it has an onboard 3.3v regulator.So 5v can be safely provided as supply.
But signal levels are at 3.3v only. At Rx pin of HC05 a level shifter can be safely used .
8051 UART can be interfaced with HC 05 and used for Home Automation projects easily.
