Which device used to connect Bluetooth with Arduino?

Programming the Arduino No extra library is used to connect to the Bluetooth module because the RX and TX pins of the Arduino are shorted with those of the module. All data–outgoing and incoming–will have to go through the module. Interfacing the module is that easy.

Does the Arduino Uno have Bluetooth?

Arduino Uno (or compatible board) A computer with latest version of the Arduino IDE installed. An Android smartphone with Bluetooth capability. JY-MCU Bluetooth Module.

Can a smartwatch be connected to an Arduino Uno?

I have a U80 Smartwatch from Bluetooth Watch International, which has bluetooth function. It is meant to be connected via to my smartphone (and it works perfectly). I also have an Arduino Uno board and a corresponding BLE ZS-040 bluetooth chip.

What do I need to connect Arduino Uno to Bluetooth?

As the communication between the Arduino UNO and Bluetooth module is UART, we need to use the RXD and TXD (Pins 0 and 1) of the Arduino. Before connecting the data lines, we mentioned already that Bluetooth module works on 3.3V.

How can I connect my Android phone to my Arduino?

When connecting the Bluetooth module to an Android device for the first time, we might need to enter the PIN of the Bluetooth module. It is usually provided by the manufacturer and is usually “0000” or “1234”. Bluetooth based wireless control has numerous applications like data transfer, audio transmission, phone conversations etc.

How does the Arduino relay work with Bluetooth?

The RX and TX pins of the Arduino connect to the TX and RX pins of the HC-06 Bluetooth module, respectively. The Bluetooth module receives data from the paired Android smartwatch and triggers the relay based on the received data.
