In this article we attempt to upgrade the ESP32 Web Server that we developed in our previous article. The upgrade concerns two functions of the station. The first has to do with the power supply of the device and the…
ESP32 WebServer with automatic Wi-Fi Setup
The ESP32 microcontroller has the ability to create a wifi network in two ways, either by creating an Access Point (AP) where it functions as a Wi-Fi hotspot (router) or by creating a Station (STA) where it functions as a…
ESP32 Web Server – Weather station
In this article we will see how to build a Web Server with ESP32. This Web Server will give us information about its environment such as temperature, humidity and atmospheric pressure. We will also have the ability to give it…
PID Controller
Introduction The PID Controller is a Proportional – Integral – Derivative controller or three-term controller. It is a control loop mechanism that uses feedback and is widely used in industrial control systems and in a variety of other applications that…
Distance Sensor
Ultrasonic Sensor HC-SR04 and Arduino In this article we will see how the HC-SR04 ultrasonic sensor works and how to use it with Arduino. This is the most popular sensor for measuring distance. We can use it to build obstacle…
Motion Sensor
Motion Sensor Motion is the constant change of the position of an object in space. Here I will introduce you in simple words the 9-axis sensor that monitors the change of its position in the three-dimensional space, the MPU 9250.Then I…

Step Motor
Step Motor A stepper motor is a type of DC motor that rotates in steps. When an electric current is applied, the motor rotates gradually and the speed of rotation depends on the “speed” at which you apply the electric…
