How do I control a Bluetooth relay?

How do I control a Bluetooth relay?

Open the “Wear OS” app and click the Bluetooth button on the top of the screen. Select “HC-06” from the list. Use the switch with the icon of a lightbulb or shake the watch to turn the relay ON/OFF.

How do I use a 4 channel relay module with Arduino?

Start by finding the “5V” pin on the Arduino and running a jumper wire over to the “VCC” pin on the breakout board. The VCC is the positive (power) input for the circuit. Next, run a wire from the “GND” (ground) pin on the Arduino to the “GND” pin on the Breakout Board. The breakout board now has power!

Does relay have Bluetooth?

NextGen Bluetooth Relay Interface By implementing the Bluetooth Serial Port Profile, the board will appear to your computer as a standard COM port, making it easy to communicate wireless data via Bluetooth between the PC and the device.

What is Bluetooth relay?

How does a 4 channel relay module work?

The 4 Channel Relay Module is a convenient board which can be used to control high voltage, high current load such as motor, solenoid valves, lamps and AC load. It is designed to interface with microcontroller such as Arduino, PIC and etc. It also comes with a LED to indicate the status of relay.

What is a WiFi relay?

WiFi Relay Control WiFi Relay Controllers allow wireless computer controlled switching from any computer connected to a network. Connect the WiFi Module to the desired wireless Network. Once configured you can start controlling these relays from the networking protocol of your choice.

Is there such a thing as a Bluetooth repeater?

Bluetooth repeater devices do exist, but are proprietary, not standardized. For example, this one from a German solar power manufacture, specific to their devices. Usually, Bluetooth networks are a simple star topology with a single master and one or more slaves – a piconet.

How does the Arduino relay work with Bluetooth?

This code uses Arduino’s serial communication protocol with the Bluetooth module. 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.

How can I control my Arduino with Bluetooth?

Open the “Wear OS” app and click the Bluetooth button on the top of the screen. Select “HC-06” from the list. Use the switch with the icon of a lightbulb or shake the watch to turn the relay ON/OFF. Make sure your Arduino is already uploaded with the code above.

What does White led mean on Arduino relay module?

There are two indicator LEDs on the PCB. The white LED is for Infrared Mode and the blue LED is for Bluetooth Mode. Now, if I press the push button once then the white LED will turn on which indicates the circuit is in Infrared control mode. At the Infrared mode, I can control the relay module with any IR remote (Example: TV remote).

Can you connect a smartwatch to an Arduino?

Take your Android smartwatch to the next level by connecting it to a 5V relay with an Arduino over Bluetooth. Do you want to use your smartwatch to control things around you? This can be done very easily within a few hours!
