LM35 Temperature Sensor Interfacing with ATmega32 and LED Display

Leave a Comment / LED Projects / Ibrar Ayyub

LM35 series is a low cost and precision Integrated Circuit Temperature Sensor whose output voltage is proportional to Centigrade temperature scale. Thus LM35 has an advantage over other temperature sensors calibrated in Kelvin as the users don’t require subtraction of large constant voltage to obtain the required Centigrade temperature. It doesn’t requires any external calibration. […]

Atmega 32u4 Based USB Controlled LED Series

Leave a Comment / LED Projects / Ibrar Ayyub

Throughout this USB series, different types of USB devices have been designed and developed. These devices were enumerating with the host computer and then were using Class Specific transfers for further USB communication. Like the Keyboard, Mouse and joystick devices were using interrupt transfers for their operations after enumeration. Similarly, the audio class devices were

0-99 Counter using AVR Microcontroller

Leave a Comment / LED Projects / Ibrar Ayyub

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

8×8 LED Matrix Interfacing with AVR Microcontroller

Leave a Comment / LED Projects / Ibrar Ayyub

In this session we are going to design an 8×8 LED display with 8×8 LED matrix and ATmega8 microcontroller, which can show alphabets or names. A 8×8 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 be made by circuiting 64
