How do I connect my HC-05 Bluetooth module to Arduino Uno?
Here, we will transmit data from Smartphone via Bluetooth to the Arduino Uno and display it on Serial Monitor of PC. Download and install a Bluetooth terminal application on your phone and use it to connect to the HC-05 Bluetooth module. Data is sent from the Smartphone using the Bluetooth terminal application.
What is the use of HC 05 Bluetooth module?
HC-05 Bluetooth Module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup. Its communication is via serial communication which makes an easy way to interface with controller or PC.
How do I connect my Bluetooth module to my laptop?
Select the HC-05 Bluetooth Module on the display and double click the Serial Port Icon to connect. Key in default passwords: 1234 on [Passkey] to connect HC-05 Bluetooth Module. After key in correct passkey, the window will show which serial COM is connected to HC-05 Bluetooth Module.
How to connect Arduino with hc-05 Bluetooth module?
Download, install, and open Bluetooth Terminal. – click “HC-05”, and “connected: HC-05” should appear at the top of the screen. Once connected, the LED on the HC-05 will blink quickly twice every 2 seconds or so. OK, so the connection is working, now let’s try to send data from the Arduino to the Android device.
How to interface Bluetooth module with Arduino Uno?
This article explains how to interface a Bluetooth module with HC-05 with Arduino Uno. Bluetooth is a one of the great example for wireless connectivity. It is used in many fields. Bluetooth consumes very small amount of energy. Do you know about Smartphone controlled robot or car.
Is the hc-05 break out board compatible with Arduino?
The EGBT-045MS Bluetooth modules (the smaller daughter board) is a 3.3v device. The HC-05 break out board has a 3.3v regulator that allows an input voltage of 3.6v to 6v but the TX and RX pins are still 3.3v. This means you can use the 5V out from the Arduino to power the boards but you cannot connect the Arduino directly to the HC-05 RX pin.
What is the UART pin on an Arduino Uno?
This pin is used to send AT command when the module is in command mode. And it is used to send data to the connected device when the module is in data mode. TXD : This is UART TX pin. This pin is used push out responses to AT command when the module is in command mode.
