  L293D is a dual H-bridge motor driver integrated circuit that allows you to control the direction and speed of two DC motors simultaneously. In this tutorial, we will go over how to use the L293D motor driver with Arduino to control the movement of DC motors. Whether you are a beginner or an experienced engineer, you will find this guide helpful. Introduction to L293D Motor Driver LThe L293D is a dual H-bridge motor driver integrated circuit that allows you to control the direction and speed of two DC motors simultaneously. This versatile IC is a popular choice for controlling motors in a wide range of applications, from small robots to automation systems. The L293D is a 16-pin integrated circuit that is designed to drive DC motors. It works by applying a voltage to the inputs, which then outputs a controlled current to the motors. This current is what drives the motors and changes their direction and speed. The L 293D is capable of driving motors up to 600mA, making it i

  NodeMCU IP Address: The NodeMCU is a popular development board for IoT projects. It’s small, affordable, and comes with built-in Wi-Fi connectivity, making it the perfect choice for creating connected devices. But before you can start building your NodeMCU projects, you need to know the IP address of your device. This IP address is essential for communicating with the NodeMCU from another device, such as a computer or smartphone. In this article, we’ll show you how to find the NodeMCU IP address, so you can get started with your next IoT project. Method 1: To Know the NodeMCU IP Address One of the easiest ways to find the NodeMCU IP address is by using the serial monitor in the Arduino IDE. First, connect your NodeMCU board to your computer using a micro-USB cable. Then, upload the following code to the NodeMCU: #include <ESP8266WiFi.h> void setup() { Serial.begin(115200); Serial.println(); Serial.print("Connecting to "); Serial.println("

 Power Supply Selection for Project: Powering up your projects (Robotics, IoT, Mechatronics, Automation, etc.) means providing its parts (micro-controller, sensors, actuators, etc.) with right supply. These parts require different supplies of different current capabilities. In this article you will know about different powering method and their characteristics.     How to select power supply for the project? What is a supply? When you build any project like robots, mechatronics, automation, IoT projects you will need to consider how you will supply it with power. In fact, some parts, such as micro-controllers and sensors, typically require either 5 or 3.3V. They also need a stable (regulated) voltage supply. Other parts may need 12V such as motors. This require several different supplies with different current capabilities. In this post, different ways of supplying power to your project are presented and discussed. Battery Your main power source is always a DC battery. Batteries come i
