LED Blinking with ATmega32 Microcontroller

Blinking LED is the first step you would like to take to get started with electronics. In this tutorial we are going to connect an LED with ATmega32, which is an AVR series microcontroller. We are going to blink the LED at half a second rate. [caption id="attachment_34936" align="aligncenter" width="600"] Blinking LED with ATmega32 AVR Microcontroller[/caption] Components Required  Hardware: ATmega32A Micro ...

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 ...

Power LED Dimmer using ATmega32 Microcontroller

In this project we are going to use one of the features of ATmega32A to adjust the brightness of 1Watt LED. The method that is used to adjust the speed of  LED is PWM (Pulse Width Modulation). The method of PWM is explained here. Consider a simple circuit as shown in figure. [caption id="attachment_34927" align="aligncenter" width="600"] 1 Watt LED Dimmer using ATmega32 Microcontroller[/caption] Now if the ...

0-99 Counter using AVR Microcontroller

In this tutorial we are going to design a 0-99 counter by interfacing two seven segment displays to ATMEGA32A Microcontroller. Here we count events based on number of times button is pressed. Before moving ahead, let's understand what is a seven segment display. A seven segment display got its name from the very fact that it has seven illuminating segments. Each of these segments has an LED (Light Emitting ...

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 ...

8×8 LED Matrix Interfacing with AVR Microcontroller

In this session we are going to design an 8x8 LED display with 8x8 LED matrix and ATmega8 microcontroller, which can show alphabets or names. [caption id="attachment_34818" align="alignnone" width="650"] LED Matrix Interfacing with AVR Microcontroller[/caption] A 8x8 LED matrix contains 64 LED (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name LED matrix. These matrixes can b ...

Scrolling Text Display on 8×8 LED Matrix using AVR Microcontroller

In this tutorial we are going to design an 8x8 LED Matrix Scrolling Display using ATMEGA32, which will show scrolling alphabets. 8x8 LED Matrix contains 64 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix, hence the name is LED matrix. We are going to make this Matrix by soldering 64 LEDs on to the perfboard or DOT PCB. The LEDs can be of any color, choose the ones which are available ...
