Interfacing LCD with ATmega32 Microcontroller

To establish a good communication between human world and machine world, display units play an important role. And so they are an important part of embedded systems. Display units - big or small, work on the same basic principle. Besides complex display units like graphic displays and 3D dispays, one must know working with simple displays like 16x1 and 16x2 units. The 16x1 display unit will have 16 characte ...

Temperature Measurement using LM35 and AVR Microcontroller

In this project we are going to design a circuit for measuring temperature. This circuit is developed using “LM35”, a linear voltage sensor. Temperature is usually measured in “Centigrade” or “Faraheite”. “LM35” sensor provides output based on scale of centigrade. LM35 is three pin transistor like device. It has VCC, GND and OUTPUT. This sensor provides variable voltage at the output based on temperature. [ ...

RFID Based Voting Machine

We know in offices, shopping malls and in many other places where only the person with authorization card is allowed to enter the room. These systems use RFID communication system. RFID is used in shopping malls to stop theft as the products are tagged with RFID chip and when a person leaves the building with the RFID chip an alarm is raised automatically. The RFID tag is designed as small as part of sand. ...

Touch Keypad Interfacing with ATmega32 Microcontroller

In this tutorial we are going to interface a 4x2 (8 key) touch keypad with ATMEGA32A microcontroller. We all know keypad is one of the most important input devices used in electronics engineering. This module does not have actual keys, but have specially designed capacitive metal pads, and these pads are very sensitive. So when a person gets in contact with one of the pads, there will a capacitive change in ...

4×4 Keypad Interfacing with ATmega32 Microcontroller

In this tutorial we are going to interface a 4x4 (16 key) keypad with ATMEGA32A microcontroller. We know that keypad is one of the most important input devices used in electronics projects. Keypad is one of the easiest ways to give commands or instructions to an electronic system.

Alarm Clock using ATmega32 Microcontroller

In this project we are going to design a simple Alarm clock using ATMEGA32 timers. ATmega32A microcontroller has a 16 bit timer, and we will be using that timer to count the seconds and develop a digital clock. [caption id="attachment_34830" align="aligncenter" width="650"] AVR Microcontroller Based Digital Alarm Clock[/caption] All the digital clocks have a crystal inside of them which is the heart of cloc ...

Interfacing Analog Joystick with AVR ATmega32

If you have played games on console you must be knowing what a joystick is. In games a joystick is generally used to control the motion of character or a vehicle (like plane or car). Joystick give a very realistic two dimensional control! Joystick are also used to control the motion of real objects like a robot or a car. Generally we want to control the back and forth motion of any object along with the abi ...
