In this project, an application was developed in Android Studio that allows users to download it and create an account to create new player for de game. In the app, users can enter their player's data, such as name and age. Once saved, this data is stored in Firebase. Users can also see their score.

The project aims to develop an interactive memory game using a 4x4 RGB WS2812B LED matrix, controlled by a joystick. The system includes a user interface with a menu that allows playing, viewing scores, and entering new players, storing the data in a database via a Wi-Fi connection. The LED matrix lights up with pairs of colors for 10 seconds before turning off, leaving one white LED on to represent the player. The player moves across the matrix with the joystick, revealing colors and trying to match pairs. The system is powered by 3.7V rechargeable batteries and uses One-Wire communication for the LEDs. The project design considers an operating temperature range of -20°C to 50°C, a voltage range of 3.3V to 7.4V, and IP20 protection for indoor use.

Game Rules for Kids

Game Scores:

Local Score: The score you achieve while playing.

Global Score: The score stored in the cloud that shows your total progress.

How to Earn Points:

Correct Matches: Each time you find a correct pair of colors, you earn 1 point in your local score.

Mistakes: Each time you make a mistake, you lose 1 point from your local score.

At the End of the Game:

Total Points: All your correct matches and mistakes are totaled.

Negative Score: If you have more mistakes than correct matches and your local score is negative, you will be given 1 point for completing the game.

Positive Score: If you have more correct matches than mistakes, your local score will be the difference between your correct matches and mistakes.

Global Score:

Final Sum: Your local score is added to your global score.

Viewing: You can see your global score in the "View Scores" section.

In this project, an application was developed in Android Studio that allows users to download it and create an account to use a pet food dispenser. In the app, users can enter their pet's data, such as name, breed, amount of food, and age. Once saved, this data is stored in Firebase. Users can also edit or delete their pet's data whenever they want.

The food dispenser can be controlled from anywhere in the world, as long as the user and the dispenser have internet access. To activate the dispenser, the user must press the "FEED NOW" button in the app, which changes a "Feed" attribute to 1 in the database. The dispenser is controlled by an Arduino Nano 33 IoT, which is also connected to Firebase. When the "Feed" attribute is set to 1, the Arduino sends a signal to a driver that controls a NEMA 17 stepper motor. The motor remains active until the registered amount of food for the pet is dispensed, measured by a weight sensor located under the food container. The sensor sends real-time weight signals, and when the indicated weight is reached, the gate closes, "Feed" attribute is set to 0 in the database and food stops dispensing.

If this project were to be commercialized, it could benefit not only from the sale of the dispenser but also from the sale of pet data, such as breed, age, and amount of food consumed, to pet food manufacturers, always with the users' permission. The device offers numerous benefits, as it can be controlled remotely and dispenses food accurately, helping to control the pet's diet.

The project can be improved by adding limit switches, allowing the input of more data,  providing an estimate of the monthly food consumption and a more user-friendly app with more functionalities can be developed.

Final Test de la electronic y programing of the protesis

Project to develop and implement a temperature control system for a drying room.

The system will be based on a reference signal set by the user using a potentiometer, operating in a range of 0 to 12 volts to represent the desired temperatures. The goal is to maintain the room at the temperature set by the user.

To achieve this, we will use the LM35 sensor, operating in a range of 28 to 40 °C. The system will include feedback provided by the LM35 sensor, whose signal will need to be conditioned to compare it within a range of 0 to 10 volts, as the LM35 output is a millivolt signal.

The system will also feature a fan to distribute heat in the drying room, which will be activated at 45 °C. In this case, a comparator with hysteresis is not necessary, only a simple comparator is required.

In 2018, I had the opportunity to represent my country in the sport called handball. We traveled to Bolivia to compete in the IHF Trophy tournament in the under-18 category. It was an incredible experience with my friends, and we managed to win third place against other countries in the region.
