Projects: Arduino

On this page are all the projects I've built over the years, using Arduino controllers and Raspberry Pi minicomputers. Some were on a private basis, others were within the scope of school projects.

Updated project!

01

My first ever project with an Arduino and that resulted from a challenge posed by a group of students. This Robot was built on a base consisting of four wheels, each one controlled by a motor.

After this little Robot, I never stopped, always looking to learn a little more about this new platform - Arduino. Thus, and because of my curiosity, this project has undergone several evolutions:

  1. Construction of a Robot controlled by an application installed on a Smartphone;

  2. Placement of two 3d printed supports;

  3. Addition of an ultrasonic sensor to avoid obstacles;

  4. Power system change, leading to the addition of a system that monitors the charge of 18650 batteries.

02

This robot car has some differences compared to the Car - Robot 1 project, the most recognizable being the robot's base platform, as it only has two wheels coupled to motors, while the previous one has four. In addition to this change, this car only has the obstacle detection system.

Another particularity of this robot is, with the proper code loaded on the Arduino, it works as a Radar, using the Processing software, being, therefore, a multifunctional Robot.

I built this weather station for the main purpose of learning how to send information and share that same information on the internet.

As far as evolutions are concerned, it will be built, using a 3D printer, a rain gauge, an anemometer and added a UV sensor.

04

Unlike the outdoor weather station, this is a mini station that only measures temperature and humidity values, and is therefore useful in measuring these indoor values.

This station is very useful for controlling the relative humidity in my office, as it is where my 3D printer and my filament spools are, which are sensitive to humidity.

05

With the arrival of summer and sunny days, it is necessary to take care of the sun exposure. So, I decided to build a small system that allows me to know the values of Ultraviolet radiation (UV), as well as the values of temperature and humidity, always in real time.

06

This system was born from the need to demonstrate, in a simple and practical way, the principle of radar or sonar operation, through the reflection of sound, which is taught in the eighth grade, in the discipline of Physical Chemistry.​

07

Robot Otto, which is already in version V9.0, is an open source robot  which allows multiple variations, both in its construction and in its programming.

Otto can walk, dance, make different sounds, avoid obstacles and much more. The limit is only in the imagination of those who build it.

08

This project resulted from a challenge launched by a friend, which involved the creation of a system, controlled by an Arduino, that would allow demonstrating that white light is a mixture of the three main colors, red (R), green (G) and blue (B), that is, the RGB system. Bearing in mind that I always try to combine the useful with the pleasant, this project came in handy.

With regard to the usefulness of this system, for me, it will be its use in classes on “Light and color dispersion”, which is taught in the discipline of Physical Chemistry, in the 8th year of schooling.

09

After having learned a lot with the Weather Station V1 , I decided to move on to the new version, much more complete and complex but very challenging. ​

Compared to the previous version, the following sensors and/or components were added:

  • UV light;

  • Particulate matter PM1.0 and PM 2.5;

  • Anemometer;

  • Wind gauge (wind direction);

  • Pluviometer;

  • Radiation shield.
