arduino hc-05 vs hc-06

Introduction: The Arduino HC-05 and HC-06 are Bluetooth modules specifically designed for use with Arduino microcontrollers. These modules allow you to establish a wireless connection between your Arduino and other devices, such as smartphones or computers, for easy communication and control. The HC-05 and HC-06 modules differ in terms of their functionalities and capabilities. The HC-05 module not only supports the Bluetooth Master-Slave mode but also the AT command mode, which allows you to configure various settings of the module. It can connect to multiple devices simultaneously, making it ideal for projects where you need to communicate with multiple devices at once. On the other hand, the HC-06 module only supports the Bluetooth Slave mode, meaning it can only be connected to by a master device. It does not have the AT command mode, making it simpler to use and ideal for applications where you only need to connect your Arduino to a single device. Both modules are compact in size and can be easily integrated into your Arduino projects. They provide a reliable and convenient way to add wireless communication to your Arduino projects, making them more versatile and user-friendly.
