This post explains how to upload code to ESP8266 using the Arduino IDE and a Serial-USB converter. We assume the use of an ESP-01 board, one of the cheapest and most used boards based on the device.
This post briefly explains what is the ESP8266, a very cheap SoC currently used in many IoT applications.
This post explains how to use the ULN2803A IC to control a DC motor, using an Arduino board.
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.
This post describes the HC-06 Bluetooth module and shows a simple app to turn on and off a lamp with an Arduino board.
This tutorial explains how to create an internal representation of date and time in a microcontroller, using interruptions.
