This connects the transmit (TX) pin of the HC-05 Bluetooth module to pin 10 on the Arduino. Pin 10 is configured as the RX pin in the software serial port (BTSerial), meaning it will receive data from ...

I connected the Bluetooth module’s rx to 11, tx to 10 and gn to gnd and vcc to 5v. The en pin was also HIGH (applying 3.3V) Then I powered up the arduino and also the Bluetooth module.

This project demonstrates the complete construction of Arduino LCD using Bluetooth Module. Source code Included within the article.

The First Arduino which is the Slave Arduino is connected to all the sensors and when a Sensor gets triggered the Slave Arduino sends data to Master Arduino, which is connected to the HC-05 Bluetooth ...

Creating a Bluetooth-controlled device with an Arduino Uno and an HC-05 Bluetooth module enables control of lights or even relays to manage AC appliances wirelessly using an Android smartphone.
