ESP32 para Desenvolvedores Arduino - Português Brasileiro from Udemy

O ESP32 é um microcontrolador poderoso.

Ele integra Wifi e Bluetooth, muitas GPIOs, funcionalidades de output e input analógicos, muitos protocolos de interconexão de dispositivos, um processador dual-core rápido.

Tudo isso por um preço baixo.

E o melhor de tudo: você pode utilizar o seu conhecimento e habilidades no Arduino para acelerar os seus projetos.

Especialmente se você já aprendeu como utilizar o Arduino Uno nos seus projetos, é provável que você tenha alcançado uma limitação de hardware.

Talvez seus projetos precisassem de mais memória, mais velocidade, ou mais pinos.

Com o ESP32, você pode conseguir muito mais capacidade para construir projetos mais interessantes, quase gratuitamente.

Contudo, o ESP32 não é um substituto para o Arduino.

Enquanto ele compartilha muito da interface de programação e GPIOs, você ainda precisa aprender o básico antes de você poder implementá-lo.

Este é o propósito deste curso.

Neste curso você aprenderá:

O que é o ESP32.
Quais são as múltiplas variações de módulos com este nome, e como estes módulos estão disponíveis para nós no formato de kits de desenvolvimento.
Quais são as diferenças e as semelhanças entre o ESP32 e o Arduino.
Como podemos utilizar o que sabemos do Arduino para fazer coisas baseadas no ESP32.
Como podemos utilizar as GPIOs para trabalhar com componentes simples como LEDs e botões, mas também controlar periféricos como displays, sensores (incluindo os integrados) e motores.
Como configurar a IDE do Arduino para que nós possamos escrever programas para o ESP32.
Como armazenar dados em uma memória não volátil.
Como se comunicar com dispositivos em um campo próximo e com a Internet.

Neste curso, Eu também incluí múltiplos mini projetos para demonstrar como utilizar funcionalidades como leitura e escrita de GPIOs, Bluetooth clássico, Bluetooth de Baixa Energia, Wifi, conversão digital para analógico, sensores de toque, e mais.

Projetos maiores também mostrarão a você como criar aplicações simples de Internet das Coisas (IoT) e Bluetooth, por exemplo.Se você estiver preparado para aprender mais, por favor, tenha certeza de assistir as aulas na seção introdutória para descobrir mais.
