HC-05 RX to Arduino Pin 11: This connects the receive (RX) pin of the HC-05 Bluetooth module to pin 11 on the Arduino. Pin 11 is configured as the TX pin in the software serial port (BTSerial), ...

This project is a Bluetooth-controlled car system powered by an Arduino and controlled via a Flutter application. It includes code for both the Arduino and the Flutter app, enabling Bluetooth ...

Connect Rx (pin 2) directly to TXD of the HC-05. Since pin 3 cannot be connected to RXD (as the HC-05 expects 3.3V logic levels), a potential divider with 1k and 2k resistors is used to connect RXD to ...

The App which I have made is connected to the master arduino through bluetooth. ... The Temperature and Humidity Sensor is connected to pin 9. The Main Gate Servo, Tank Servo and the Garage Servo are ...

Introduction:In Arduino environment, it's convenient to access BT SPP like a serial port and react to the command string sent from the BT serial port.

The $22 kit includes an Arduino-BLE board and 6-pin header that should be fairly broadly applicable for building Arduino-based hardware that can communicate with iOS devices.

The watch is built around an Arduino Pro Mini, a scavenged Nokia LCD, and a BlueSMiRF Gold. The Bluetooth connects to a Nokia N900 with a little Bluetooth client app [Ahmet] wrote.

Part Two : Sending datas from the Arduino to the Raspberry PI. Connect a potentiometer (10 k Ohm) to the Arduino according the the "Arduino_BT_02.jpg" file (see attachments). Power and program the ...
