The AVR microcontroller from ATMEL is widely used in embedded applications. The below list of AVR Microcontroller Tutorials and AVR Projects helps you to learn AVR series of microcontrollers from very basic level to advanced applications. Most of these projects are built with the ATmega16/Atmega32 Microcontroller and will be programmed using the Atmel Studio. All projects and tutorials are explained with neat circuit diagram, code and hardware demonstration.
An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive components can replace expensive commercial systems, giving you complete control over features while learning valuable skills in embedded programming and circuit design…
We at Circuitdigest have worked on a lot of PCB projects, but have consistently faced a challenge during the assembly process. Specifically, when working with SMD components, the use of solder paste is crucial. While SMD stencils are the most efficient method for applying solder paste to a PCB, they can be difficult to obtain,…
In this tutorial, we are going to talk about fuses. Back when I was in college and learning about all the cool things in electronics, I heard the term fuse in AVR for the first time, my initial thought on the topic was, oh! there is something inside the AVR that will blow if I did something wrong. Back then, there were not much resources available on the Internet…
GPS modules are widely used in electronics applications to track the location based on longitude and latitude coordinates. Vehicle tracking system, GPS Clock, Accident Detection Alert System, traffic navigation, surveillance system etc. are few of the examples where GPS functionality is essential. GPS provides Altitude, Latitude, Longitude, UTC time…
According to researchers from Pen state University, humans are more likely to trust machines over people, which is likely evident from us revealing our ATM pin to a machine so easily. Today, in the world where AI, Machine learning, Chat bots, Smart Speakers, Robots etc are actively progressing, this synergy between humans and robots is only set to increase. Today, from…
DC motors are the most widely used motors. These motors can be found almost everywhere from small projects to advanced robotics. We previously interfaced DC Motor with many other microcontrollers like Arduino, Raspberry pi and used it in many robotic projects. Today we learn to control DC motor with AVR Microcontroller Atmega16. But before going ahead let’s know more about…
Hall sensors works on the principle of Hall Effect proposed by Edwin Hall in 1869. The statement proposed says, “The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.”
So, what could…
Pulse Width Modulation (PWM) is a powerful technique where width of the pulse is changed by keeping the frequency constant. The technique is used in many control systems today. The application of PWM is not limited and it is used in wide range of applications such as motor speed control, measurement, power control and communication etc. In PWM technique, one can easily…
Atmega16 is a low cost 8 bit microcontroller and comes with more number of GPIO’s than its previous version of microcontrollers. It has all the commonly used communication protocols like UART, USART, SPI and I2C. It has wide applications in robotics, automobile and automation industries because of its wide community support and simplicity.
Atmega16…
Every digital clock has a crystal inside it to keep track of time. This crystal is not only present in the clock but also present in all computing real-time systems. This crystal generates clock pulses, which is needed for timing calculations. Although there are some other ways to get clock pulses for higher accuracy and frequency, but the most preferred way…
Here we will be building yet another project with AVR Atmega16 Microcontroller. If you are new to AVR microcontrollers then you can refer to previous AVR projects and tutorials.
Building a robot is always a thrill for all electronics hobbyists. And this thrill can be maximized if the robot can automatically do some things without any external…
One common feature that is used in almost every embedded application is the ADC module (Analog to Digital Converter). These Analog to digital Converters can read voltage from analog sensors like Temperature sensor, Tilt sensor, Current sensor, Flex sensor etc. In this tutorial we will learn What is ADC and How to use ADC in Atmega16. This tutorial includes…
