The ESP32, a twin core MCU from Espressif Systems with built-in Bluetooth and Wi-Fi, will be covered in this tutorial. In comparison to previous ESP controllers, ESP32 offers a substantial feature set and is a significant move forward. This Getting Started with ESP32 tutorial is intended for absolute newbies, regardless of whether they have any prior knowledge with internet of things project experience.

Introduction to internet of things – IoT

The term “Internet of Things” (IoT) describes a network of physical objects, including cars, appliances, and other items, that are network-connected, have sensors, software, and other features that allow them to communicate and gather data. Creating a seamless flow of data between the physical and digital worlds is the main objective of the Internet of Things (IoT). This will enable increased productivity, automation, and intelligent decision-making.

Starting with the Internet of Things (IoT) entails acquiring technical abilities, comprehending fundamental ideas, and investigating useful applications.

Yes, definitely! For Internet of Things (IoT) projects, the widely used and configurable ESP32 microcontroller with integrated Wi-Fi and Bluetooth functions is a great option. A quick rundown of how to get started with IoT with ESP32 and Arduino is provided here. Before moving too quickly, it’s important to understand ESP32 hardware configuration.

The hardware configuration of esp32

The ESP32 is a cost-effective System on Chip (SoC) microcontroller from Espressif Systems, the same company that created the well-known ESP8266 SoC. This 32-bit Tensilica Xtensa LX6 microprocessor has built-in Bluetooth and Wi-Fi and may operate on a single or two core bases.

The excellent part about ESP32, like ESP8266 is its inbuilt RF components including Power Amplifier, Low-Noise Receive Amplifier, Antenna Switch, Filters and RF Balun. As a result, building hardware using the ESP32 is rather simple because very few external components are needed.

It should be straightforward to create battery-operated applications using ESP32, such as wearables, audio equipment, baby monitors, smart watches, etc.

ESP32 specifications

Including every specification in this Getting Started with ESP32 guide is a not suggestable. Below is an overview of some of the ESP32’s most significant specifications. Nonetheless, I highly suggest reviewing the Datasheet for the full set of specs.

  1. Dual-Core Processor:
    • With its dual-core Xtensa LX6 processor, the ESP32 offers enhanced performance and more effective multitasking.
  2. Wireless Connectivity:
    • With built-in Bluetooth (Bluetooth Low Energy, BLE) and Wi-Fi (802.11 b/g/n) capabilities, the ESP32 is appropriate for a variety of Internet of Things applications that need wireless connection.
  3. Processor Speed:
    • Operating at up to 240 MHz, the processor offers significant processing power for a wide variety of applications which include fundamental tasks to complex calculations.
  4. Ultra-Low Power Consumption:
    • The ESP32 is appropriate for battery-powered applications since it is made with energy conservation in mind. It has multiple power modes and sleep modes to reduce power usage.
  5. Peripheral Interfaces:
    • A wide range of peripheral interfaces, such as GPIO (General Purpose Input/Output), I2C, SPI, UART, and others, are available on the ESP32, giving users the freedom to connect to a variety of displays, sensors, and other devices.
  6. Analog-to-Digital Converter (ADC):
    • The ESP32’s ADC enables analog sensor readings. Compared to certain other microcontrollers, it offers more precise readings thanks to its 12-bit resolution.
