AVR is the name of the family of microcontrollers designed by the Atmel company and introduced to the market in 1996. They designed these microcontrollers with the RISC command set on the modified Harvard architecture. Microcontrollers are 8-Bit and, as an exception, it produced in 32-bit models in a period. It is one of the most widely used microcontrollers in many embedded systems and especially in hobby circuits, and forms the basis of Arduino. ...

Hi all!! Introducing Optiboot! When you look at the photo below, you can see “What is Optiboot? but this is the place..” 😁 Yes, the part you see is called Optiboot. So what is this Optiboot? It is a small and fast bootloader for Arduino and other Atmel AVR chips. Arduino owes much of its ease of use to its bootloader. The bootloader is software built into the Atmega microcontroller that is responsible for making it easy to upload a new draft from the Arduino IDE to the microcontroller’s memory. ...

Hello everyone, in this article I will tell you what DHT11 and DHT22 are, their features, and detailed use. Come easy! 😁 What Are DHT11 and DHT22, and What Are They Used For? DHT11 or DHT22 is a small sensor used to measure humidity and temperature in the environment. It is used to measure data and humidity in % of various heat units in Celsius, Fahrenheit, and kelvin values. DHT22 has better properties, is more stable, and is more expensive. ...

Hello, in this article we will learn how to download a library to the Arduino IDE, how to add it, how to solve the library error and how to delete it. Let’s get started! If you haven’t installed the Arduino IDE, you can download and install it by watching below. Libraries can be added in 3 ways: ...

I highly recommend checking out the Big Guide 1 before looking at this blog! 😉 Required Materials: Arduino Uno (Arduino Nano, Arduino Mega etc.) Breadboard 16×2 LCD Screen (Green or Blue) 😄 Assorted Men-Male Jumper Cable 10KΩ Potentiometer (For backlight counter, optional) 220RΩ (We will use in the examples) LCD and Arduino Connections The diagram of the pins on the LCD we use is as follows. We have 16 pins on our LCD screen. Depending on the screen we are going to use, the pins can be on the top, bottom, or both sides of the screen. Some very rare screens have 14 pins because there is no backlighting light. Pins 15 and 16 are used to light up the backlight on displays with display lighting. The backlights are separate from the LCD, so we can use the pin of the backlight by plugging it into a digital port. The connections from each pin to the Arduino will be the same, but it can arrange differently you can pins via the LCD. You can look at the LCD’s datasheet for this. ...
