It is an IDE by Atmel for developing and debugging Atmel AVR microcontroller. It provides an environment to write, build and debug your applications that are written in C/C++ or assembly code.
- Getting Started with Atmel Studio 6: In this project, we learned how to use the Atmel Studio 6 and how to make the first project in Atmel Studio 6. It is very easy to use in which we can build any type of application as per requirement. For complete guidelines we follow these steps to start with Atmel Studio 6;
- Download Atmel Studio 6 Website: www.atmel.com
- Open the Atmel Studio
- After the installation. The installation process is very eas
- Create a New Project
- Device Selection
- Write a Program
- Compile the Code
- Select Programmer
- Device Programming
- LED Blinking using ATMEGA32 AVR microcontroller: In this tutorial, we learned about the AVR Atmega32 and its programming and also how to develop the code for blinking LED through Atmeg32.First, we will write code using C language in Atmel Studio 6. For Atmega32 programming we used two registers DDR and PORT. DDR tell us the pin of Atmega32 input or output and PORT tell us whether pins are active low or active high.For the code and simulation for this project please visit
- How to use push button with ATMEGA32 AVR microcontroller: This tutorial is for beginners in the field of Atmel AVR programming. I hope that you read my first tutorial Blinking LED using Atmega32 and Atmel Studio. In this topic, we will learn what push button is and how we can use push button with AVR microcontroller Atmega32. What is Push Button? It is a small controlling device that’s operated by the electrical device by pressing. Here a push button is used to switch with a microcontroller. For the code and simulation for this project please visit
- LCD interfacing with ATMEGA32 AVR microcontroller: In this tutorial, we will discuss LCD and interfacing with Atmega32 AVR microcontroller.16×2 LCD is a module which is used to display the character. It is a very basic module which is commonly is used in many electronic devices and project. It can display 2 lines of 16 characters. 16×2 LCD can be interfaced with a microcontroller in 8 Bit or 4 Bit mode. These differ in how data and commands are sent to LCD. In 8 Bit mode, character data (as 8 bit ASCII) and LCD command are sent through the data lines D0 to D7. That is 8-bit data is sent at a time and data strobe is given through E of the LCD.
- DC motor interfacing with Atmega32 and L293D: In this tutorial, we learned about DC motor, how to interface with AVR microcontroller and also learned about motor driver L293D. Directly connect the DC motor to a microcontroller is not a good because the motor needs more current else the microcontroller provide current. So to solve this problem we use a motor driver to interface with a microcontroller. We use IC like L293D or L298.
- DS18S20 interfacing with PIC and AVR microcontroller: In this tutorial, we will discuss DS18S20 and how to interface with PIC and Atmega32 microcontroller. DS18S20 is a 9bit digital thermometer that is used to measure the temperature in Celsius. It communicates with only one wire with microcontrollers.
- Optocoupler interfacing with AVR PIC and 8051 microcontrollers: In this topic we learn about the Optocoupler, working of the Optocoupler and how to interface with AVR, PIC, and 8051 microcontrollers. What is Optocoupler? It’s also known as Optoisolator. It is an electrical component that interconnects with two separate electric like that is used to transmit input signal by light sensitive.
- How to use timers of AVR microcontroller: In this topic, we discussed AVR timer and how to use the timers of AVR in different projects as required. AVR ATmega32 consists of three timers Timer0, Timer1 and Timer2 respectively. Two timers are 8 bit registers whereas thee one is a 16 bit register.
