How to use Push Button with ATMEGA32 AVR Microcontroller

This tutorial will provide an understanding of push buttons and their integration with the AVR ATmega32 microcontroller. While push buttons can be applied to control various devices, we will focus on using them to manipulate an LED in this demonstration. Additionally, we will delve into the utilization of “if and else” statements in the C […]

The LED Chasing Effect Project using Atmel AVR Microcontroller

The LED Chasing Effect Project using Atmel AVR Microcontroller

One of the interesting projects for most of the embedded beginners enthusiasts or hobbyists is to build the LED chasing effect. In this project we are going to use both the Arduino IDE and Atmel AVR Studio to program the AVR ATMega168 microcontroller, therefore you could learn to use these well known Integrated Development Environment

LED Sketchpad

LED Sketchpad

In this project we built a sketchpad based on LED matrix display with microcontroller and resistive touch screen control. We used a single point resistive touch screen to detect the user’s gesture and microcontroller’s analog/digital converter (ADC) ports collects the data and convert it to coordinates. We designed a LED drive circuit with shift registers

ukule-LED

ukule-LED is a ukulele with LEDs embedded in its fretboard. These LEDs can light up in configurations corresponding to different chords, which can aid the ukulele player in learning how to play certain chords, or can act as a chord reference for a more advanced player. ukule-LED has two modes of operations. First, in “play”

Sound Acquisition Subsystem Circuit Diagram

Frequency Visualizer

Introduction This project visually displays the frequency content of an audio signal using an 8X3 grid of LEDs. A microphone and amplifier collect analog audio input which is sampled digitized using the MCU’s analog-digital converter. The samples are buffered and and a 32 point discrete cosine transform is performed in real time to obtain 32
