What is NodeMCU? NodeMCU is actually the name of a firmware developed to program ESP8266 with the Lua language. Since such Dev Kit cards are very popular, these cards are called NodeMCU for short. Since NodeMCU is an open source platform, the hardware design is open to editing, modifying, and rebuilding. The NodeMCU Dev Kit/board consists of the ESP8266 wifi-enabled chip. The ESP8266 is a low-cost Wi-Fi chip developed by Espressif Systems with the TCP/IP protocol. ...

Hello everyone, in this blog, I will tell you what HC-SR04 is, its features, and detailed use. Come easy! 😁 What is and How Does It Work HC-SR04 is an ultrasonic sensor, i.e. Sound Navigation and Ranging. Sonar is a sensor that calculates the distance to the opposite object or object using communication. Sonar allows us to calculate the distance to the object using sound waves. It can measure distances between approximately 2cm and 400cm. ...

The Arduino IDE 2.0 is really a great project! So why the (Pro) IDE? The simple IDE had a lot of missing features. This made it a really great app by adding a lot of features for convenience for larger and larger projects. 🙂 This program, which has completed its development phase, is now trying to provide a good experience to its users in version 2.0. So what features does the IDE have? ...

If you are searching for “Arduino Uno download”, the software you actually need is the Arduino IDE: the free official program that lets you write code for the Arduino Uno (and every other Arduino board) and upload it to the board. This guide walks through downloading and installing the current release, Arduino IDE 2.3.10. To learn more about the boards themselves, read the History of Arduino first. 🙂 Prefer to watch instead of read? The 36-second walkthrough below covers the whole process. (It was recorded during the 1.8.x era, so arduino.cc has been redesigned since and downloading now takes fewer steps. Follow the written steps below for the current screens.) ...

Hello everyone! In this article, we will connect a 16x2 LCD to Arduino over I2C. Using an I2C LCD with Arduino cuts the wiring from 12+ pins down to just 4 (VCC, GND, SDA, SCL), which keeps your projects much cleaner. Let’s get started! Read This! If you want to learn more about the 16x2 LCD Screen in more detail and how to use it without I2C, you can find out by clicking here. This blog will also be supported with guide blogs. ✨ ...
