Book: "Autonomous Cars with Neural Networks"








"This book contains information about two projects with autonomous robots and with the purposes shown below:


Machine learning and PID controller allow us to control an autonomous car to drive around an object. 


Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet C light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification, or treat biologically contaminated surfaces. Recent studies have shown that UV short-wave radiation is capable of eliminating COVID-19 viruses at the hospital level, thus improving the cleanliness of the intensive care area, general medicine rooms and individual rooms. Covid-19 is continuing to spread around the world, with around 246 million confirmed cases and more than 5 million deaths across almost 200 countries. Today health is a priority; and as main goal, this innovative idea helps us thrive in this new normal because has cost effective and useful to sanitize the whole home or objects by using artificial intelligence and voice commands."

Book: "Smart Robot Arm"








"This design utilizes robotics in as a personal assistant! This is a collaborative robot arm in two versions to assist you in several tasks. The main goal is design a Collaborative Robot Arm with Artificial Intelligence, and Used as Assistant in: 1) Voice Command System and 2) Sorting Objects System.



Here the main functions to my first version are: a) controlling a bottle, b) controlling a bradboard, and c) controlling a box. Here I am using Artificial Intelligence (AI), but with hardware as Alexa Echo Dot, ESP32-WROOM-32, and Arduino Nano 33 BLE Sense; and free open source tools: FauxmoESP library.



Finally my last version, here I'm sorting objects by color and using TensorFlow with Arduino Nano 33 BLE Sense and Arduino Nano 33 IOT, this system detects blue, green and red balls to place them in their corresponding container."

Book: "Collection of Raspberry Pi Projects"


Chapter 1. Introduction 

Chapter 2. Alarm System

Chapter 3. Gas Leak Alarm

Chapter 4. Weather Station

Chapter 5. Digital Image Processing

Chapter 6. Animations With Python And Pygame


"This book is a collection of my best publications on projects made with the Raspberry Pi board, and which I describe below:

Alarm System: Develop an alarm system to detect the movement of someone through the use of a PIR motion sensor and the Raspberry Pi Zero W board. When this happens, an alert notice will appear on the Twitter account.

Gas Leak Alarm: Develop a system for the detection of fires or gas leaks with the Raspberry Pi Zero W board and the MQ2 gas sensor. This system can send the captured data to the remote server of ThingSpeak. When a gas increase is detected beyond a limit, then a message is sent to the Twitter account.

Weather Station: Develop a Weather Station with a Raspberry Pi Zero W board, and monitor all the sensors with ThingSpeak and Twitter. The sensors used are DHT11 (humidity and temperature sensor) and BMP085 (barometric pressure and temperature sensor). Also, you can use new versions of this sensors without any problem.

Digital Image Processing: Make use of digital image processing with OpenCV on a Raspberry Pi 3. To achieve this goal, start from the software installation to make your own object classifiers and finally make an example to manipulate an object by means of an image in movement. This has many applications, ranging from recognizing people or objects, to creating your own video surveillance system.

Animations With Python And Pygame: The main goal of this project is to develop virtual animations of a human, animals and objects that are moved on a stage or image background. We will use Python and Pygame, these software tools are used to program games."

Book: "Collection of Arduino Projects"



Chapter 1. Introduction

Chapter 2. Astronomical Clock

Chapter 3. RF Remote Control

Chapter 2. Three LED´s Lightness Control With Android Studio

Chapter 2. Automation Home With Arduino UNO

Chapter 2. Weather Station With Arduino UNO

Chapter 2. IoT Aquarium Monitoring




"This book is a collection of my best publications old and new on projects made with the Arduino UNO board or with the Arduino IDE programming tool:

Astronomical Clock: This is a clock and calendar, also we can see on the TFT screen the astronomical data of the Moon in real time, making use of the DS3231 clock module.

RF Remote Control: This project shows us how we control a "Micro Robot Car" by mean of using a RF Remote Control, and a magnetic control (Infineon 3D Magnetic Sensor 2Go).

Three LED´s Lightness Control with Android Studio: In an android application we are going to control the lighting of three LEDs by means of sliding bars. An application of this project is the control of the lighting of a house.

Automation Home with Arduino UNO: this project is an example of a smart home prototype developed with Arduino UNO and App Inventor 2. We will be using a conventional Smartphone. The modules used are: HC-05 Bluetooth, PIR Motion Sensor, DHT11 Humidity Sensor, MQ2 Gas Sensor, LDR Light Detection Sensor, Servo, Fan and LED.

Weather Station with Arduino UNO: here I show you three examples of weather stations, the most important is the third, where the data sampled by the Humidity and Barometric Pressure sensors are captured and sent to the NOKIA LCD screen and to the serial port, later these data are graphically displayed on the computer through an application made with Visual Basic 6. The application is also programmed to save the data in a database made with SQL Server.

IoT Aquarium Monitoring: In this project I demonstrate that it's possible to use our technologies to monitor and protect life in water, aquariums, rivers, lagoons and seas. I've used the following technologies: Amazon Web Services, Soracom Air Global IoT SIM, and Seeed Wio LTE US version 4G, which is an Arduino and Grove compatible development board."

Book: "Projects with IOTA"


Chapter 1. Introduction

Chapter 2. Software Installation

Chapter 3. Air Quality System v1

Chapter 4. Air Quality System v2

Chapter 5. Waste Monitoring System



"In this book you will find three projects in which we will use the IOTA protocol, and the JavaAcript and Node.js programming languages; We will learn how to develop Healthy Indoor Environment Systems for smart commercial buildings using Authenticated Masked Messaging (MAM) of the IOTA protocol. Below I give a sketch of the content of this book:  

Air Quality System v1: we're going to simulate a system for monitoring the humidity and temperature of an intelligent building located in Mexico City. Remotely we can know the values ​​of these parameters and then we can take measures to control them, or anything else.

Air Quality System v2: we've improved the version of our system, and we've added two more sensors, that is, an LP Gas sensor and a Carbon Monoxide sensor. We have simulated this system in a smart building in New York City, and with this version we can know if there is a gas leak and / or a fire in our smart building.

Waste monitoring system: here we're going to monitor all garbage waste in a smart building located in Berlin. We all know that these wastes emit unpleasant odors that damage the health of those who live or work in these smart buildings."
