In this video, we will learn to use the GPIO of the microcontroller. At first we will learn to drive an output device like an LED. And at the later part, we will learn to read an input device like a tactile button switch. 

For your reference, copy of the…

In this video, we will learn 2 ways to read the state of an input device like a button switch. Firstly, is by using a polling method and secondly, by using interrupts. At the last part, I will demonstrate an example of controlling a DC motor with limit switch…

In this video we will be talking about PWM or Pulse Width Modulation using ESP32. We will learn how to access the PWM frequency and duty cycle to control the speed of DC motor

In this video we will learn how to create a web server hosted in ESP32 using MicroPython language for controlling the state of a gpio pin. 

This knowledge can be use for controlling a relay which is popular in home automation projects. For the sake of simplicity…

In previous video, we learned to create a web server on ESP32 acting as a wifi station mode. Now in this video, we will learn another wifi mode which is an Access Point mode.


In Access Point mode, you dont need a router. ESP32 will act as the Access Point…

In this video we will learn to create a web server hosted on ESP32 and display DHT measurement readings on it. We will use AJAX to automatically update the sensor values without refreshing the whole web page.
