Lorenzo Brum Cavalcante Portfolio on Moonpreneur

About

Hello, My name is a Lorenzo Cavalcante, and today I am going to show you my project about binary and logic gates. My project explains how computers use only two numbers, 0 and 1. Binary can look confusing to people, but computers understand it easily.

My Finance tracker

Hi, my name is Lorenzo. I am 11 years old, and I have five pets. I like robots and coding. Today I am going to show you my project, which is My Finance tracker web app. I created it using Python, Streamlit, Pandas, Matplotlib, and WordCloud. The app lets users add expenses by entering the date, category, description, currency, type, and amount. It can also display expenses, create charts, and make a word cloud. My project shows spending information, such as spending on housing, education, savings, and taxes. I worked through many coding errors to make my project work.

Box counter bot

Hi, my name is Lorenzo, and I am 11 years old. I like robotics and fashion, and I enjoy creating new things. I have four pets: Ruby the hamster, Caramel the explorer kitty, some guinea pigs, and Toby the dog. My project is a smart warehouse robot that can count boxes and move around the warehouse. It uses IR sensors to detect boxes, ultrasonic sensors to detect obstacles, motors for movement, and a buzzer for sounds. The robot counts boxes as it scans them and can perform a U-turn when needed. My goal was to create a robot that could solve warehouse problems.

Binary

Hello, My name is a Lorenzo Cavalcante, and today I am going to show you my project about binary and logic gates. My project explains how computers use only two numbers, 0 and 1. Binary can look confusing to people, but computers understand it easily. In my presentation, I explain what binary is, how to read binary numbers, and how to add them. I also show examples like 1, 10, 11, 100, and 101. I explain how numbers can be regrouped when adding, similar to stacking blocks or playing Tetris. I made this project to help others understand the basics of computer language.
