The objective of this post is to explain how to control a passive buzzer module using an ESP8266.
The objective of this short post is to explain how to solve the error opening the awt.dll file, during the installation of the Arduino IDE.
This post describes one of the basic laws of circuit analysis, more precisely KVL (Kirchhoff’s Voltage Law), which states that the sum of all voltages in a closed loop of a circuit are equal to zero.
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.Continue reading “Using a ULN2803A to control a DC motor”
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 post describes a prototype of a smart medication dispenser, created with an Arduino as the controlling unit. The hardware platform and the software to support all the functionalities were created from scratch. Some of the functionalities include the possibility to connect the dispenser to a smartphone using HC-06 bluetooth module, or to communicate with a remote server through the internet, using ESP8266 Wi-Fi module.
This tutorial explains how to create an internal representation of date and time in a microcontroller, using interruptions.
