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.

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.

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

Apr 26, 2024 · In this project, we will learn about HC-05 Bluetooth Module, how to interface this Bluetooth Module with Arduino and how the HC-05 Bluetooth Module can be used for controlling the Arduino Board over Wireless Communication (Bluetooth).

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 the HC-05 Bluetooth Module and interfacing it with Arduino UNO. Later we will also show you how to set up a wireless connection between the HC-05 module and an Android phone.
