ESP8266: Reading temperature with the DS3231 RTC
The objective of this post is to explain how get the internal temperature measurements of the DS3231 using an ESP8266 and an easy to use Arduino library.
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.
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.
