The AVR is a modified Harvard architecture 8-bit RISC single chip microcontroller where program and data are stored in separate physical memory systems that appear in different address spaces, but having the ability to read data items from program memory using special instructions.
Once check the list of projects in which AVR microcontroller are used. You may get detailed information about all those projects by clicking on any of the particular project idea. You would get the circuit diagram and as well as the working of that particular project also.
AVR Microcontroller Projects:
| Temperature Controlled DC Fan using Microcontroller: The main principle of the circuit is to switch on the fan connected to DC motor when the temperature is greater than a threshold value.This can be used in home applications and in cpu to reduce heat. | |
| Biometric Attendance System using Microcontroller: This finger print based attendance system is designed using AVR Microcontroller. This can be used in industries, schools, colleges, etc. | |
| PWM based DC Motor Speed Control using Microcontroller: Here is a simple DC Motor speed control circuit designed using AVR Microcontroller. Here we use a technique called PWM (pulse width modulation) to control the speed of DC motor. | |
| Density Based Traffic Signal System using Microcontroller: In this system, we use IR sensors to measure the traffic density. We have to arrange one IR sensor for each road; these sensors always sense the traffic on that particular road. All these sensors are interfaced to the microcontroller. Based on these sensors, controller detects the traffic and controls the traffic system. | |
| Line Following Robotic Circuit using ATMega8 Microcontroller: This line follower robot is a basic robot that follows a specific path indicated by a line having some particular width. | |
| Sun Tracking Solar Panel: This article describes about circuit that rotates solar panel. This Sun tracking solar panel consists of two LDRs, solar panel, stepper motor and ATMEGA8 Microcontroller. | |
| Street Lights that Glow on Detecting Vehicle Movement: This article describes about the circuit that switches the street lights on detecting vehicle movement and remains off after fixed time. This system controls the street lights using light dependent resistor and PIR sensor. | |
| Auto Intensity Control of Street Lights: This is a simple circuit that automatically controls the intensity of street lights which is designed using microcontroller and LEDs. | |
| RFID based Attendance System: This simple RFID based attendance system is designed using ATmega8 Microcontroller and is mainly used in educational institutions, industries, etc. where authentication is needed. | |
| Digital Temperature Sensor: The main principle of this circuit is to display the digital temperature value. These are mainly used in environmental applications. | |
| 2 Digit Up Down Counter: The main principle of this circuit is to increment the values on seven segment displays by pressing the button. This circuit can be mainly used in scoreboards. | |
| DTMF Based Home Automation System Circuit: This is a simple and very useful circuit in our real life named DTMF controlled home appliances system. It helps to control the home appliances using DTMF technology. | |
| Water Level Indicator: This Water Level Indicator project employs a simple mechanism which helps to detect and indicate the water level in an overhead tank or any other water container. It can be used in Hotels, Factories, Homes Apartments, Commercial Complexes, Drainage, etc. | |
| Interfacing 16X2 LCD to AVR Microcontroller: This is a circuit which helps in interfacing 16X2 LCD with AVR Microcontroller. The Atmega16 belongs to the AVR microcontroller family. | |
| Automatic Railway Gate Controller with High Speed Alerting System: The main aim of this project is to operate and control the unmanned railway gate in the proper manner in order to avoid the accidents in the unmanned railway crossing. | |
| Boolean Algebra Calculator: This Boolean algebra calculator is an interesting project which is more useful in our real life by working as a portable calculator to simplify the Boolean expression on the fly. In our circuit, we use Boolean algebra simplification methods like the Quine-McCluskey algorithm to simplify the Boolean expression and display the output on the display. |
