Toggling a LED with Arduino and HC-06
Following the previous post describing the HC-06 module, this one shows how to use it to build a simple program to toggle the debugging LED of an Arduino board, using Bluetooth. This tutorial assumes the use of the HC-06 integrated in the baseboard described in the previous post. Connecting HC-06 to the Arduino Board Using the previously …
Arduino Bluetooth with HC-06
This post describes the HC-06 Bluetooth module and shows a simple app to turn on and off a lamp with an Arduino board. HC-06 HC-06 is a cheap Bluetooth module that supports SPP (Serial Port Profile), which allows the establishment of an emulated serial connection using Bluetooth. This connections is transparent for the microcontroller, since the module handles all …
