In this project, we'll learn how to interface an HC-05 Bluetooth Module with an Arduino Uno. We'll establish a communication link between an Android smartphone and the Arduino, using HC-05 for wireless control.

In this Arduino Bluetooth Tutorial we will learn how use the HC-05 module for controlling Arduino via Bluetooth communication. You can watch the following video or read the written tutorial below for more details.

Mar 30, 2024 · Connect the HC-05 module to a device capable of sending and receiving serial data, such as an Arduino or any microcontroller equipped with UART. On the Bluetooth side, initiate a wireless connection between the HC-05 module and another Bluetooth-enabled device, like an Android phone.

May 4, 2022 · Step-By-Step Instructions To Connect HC-05 Bluetooth Module To An Arduino. I will show you how to connect your HC-05 module to an Arduino UNO in a few simple steps. HC05 module comes with a 2.54 mm bergstick connector. You can use a male-to-female Dupont cable to connect HC-05 and the Arduino UNO.

We will use pins 10 and 11 of the Arduino to connect the HC-05 and use the SoftwareSerial library to communicate with the module. The Hardware serial port on arduino is used to send/receive messages from the computer to the Arduino.

Jul 3, 2021 · Establish a BT connection, send command to turn LED on and off and check the status of the LED.

In this project, we will be learning how to communicate between two Arduino boards by pairing two HC-05 Bluetooth modules connected to each of the Arduino Boards. Once you plugged both of your Arduino boards into a power source, the LED on the Bluetooth modules will blink fast until they have connected to each other.

Mar 3, 2025 · HC-05 is a classic Bluetooth module that supports both Master and Slave modes. This makes it more flexible than some other modules, like HC-06 (which only works in Slave mode). It communicates with Arduino using Serial Communication (UART), making it easy to connect with Arduino’s TX and RX pins.

In this tutorial, we will explore how we can interface the Bluetooth module (HC-05) with Arduino using Arduino IDE. Also, we will build an example project that will turn ON-OFF LEDs by using a Serial Terminal Android application via Bluetooth. So, …

Apr 17, 2025 · Simply pair the HC-05 with your smartphone and send text commands to communicate with Arduino.
