Complete ESP32 tutorials starting from basics to advances level. ESP32 is a famous development board for the internet of things applications. Although, other IoT development boards are also available in the market. But this board gains popularity among embedded developers and hobbyists in a short time. Because of its on-board many features such as Bluetooth, BLE, WiFi, Crypto-Engine and many others.
In this tutorial, we will learn to create a MQTT client with ESP32 to publish sensor readings and to subscribe to different topics using HiveMQ. Our aim is to create an MQTT client that will be able to subscribe to MQTT topics and publish sensor readings on MQTT topics. We will use the PubSubClient library … Read more
In this user guide, we will build an ESP32 web server which will act as a remote serial monitor. This will be achieved by using the WebSerial library and programming the ESP32 board in Arduino IDE. Additionally, we will use the ESPAsyncWebServer library as well. The web based serial monitor will work just the same … Read more

In this tutorial, we will learn how to use ESP32 dual-core using FreeRTOS and Arduino IDE. The ESP32 development board consists of 2 Xtensa 32-bit LX6 microprocessors which makes it a dual-core microcontroller. This core0 and core1 are included for better performance and efficiency. When programming ESP32 using Arduino IDE, by default core1 is used … Read more
This tutorial focuses on an example project which shows motion detection through a PIR motion sensor. This PIR motion sensor will be interfaced with the ESP32 board and a 5mm LED. Through interrupts and timers of ESP32, the LED will be controlled. Whenever motion will be detected, an interrupt will be triggered, a timer will … Read more
In this tutorial, we will learn to use ESP32 deep sleep modes and wake up sources using Arduino IDE. In this comprehensive guide, we will look at how to put the ESP32 development board into deep sleep mode. Furthermore, we will also discuss different wake up sources through which ESP32 can go from sleep to … Read more
In a previous tutorial, we learned how to control the output of our ESP32 or ESP8266 NodeMCU by using Telegram Bot (Telegram ESP32 and ESP8266: Control GPIOs and LEDs using Arduino IDE). This time we will take our project further and use telegram to request sensor readings from the ESP32/ESP8266 board. We will create a … Read more
In this user guide, we will learn to perform over-the-air (OTA) updates to ESP32 using the AsyncElegantOTA library with VS Code and PlatformIO.This means that the ESP32 module like other Wi-Fi enabled microcontrollers has the feature to update the firmware or update files to the filesystem wirelessly. There are several ways to accomplish the OTA … Read more
