ATMega32 Microcontroller: The Ultimate Guide for Beginners

Other Projects / Ibrar Ayyub

The ATMega32 is an widely used microcontroller from Atmel. It shares many similarities with the ATMega328P but has a more reduced memory capacity. However, the ATMega32 makes up for this with a greater number of input/output pins available. A key advantage of the ATMega32 is that each GPIO pin can exclusively support either digital input/output

Infrared Universal Remote Control

Other Projects / Muhammad Bilal

Introduction One of the more challenging aspects of owning a home entertainment system is dealing with all the remote controls. My device is designed to tackle this problem. Specifically, the universal remote control I implemented is able to learn the signals used by other remote controls, store those signals in its own memory, and send

LED Sketchpad

LED Projects / Muhammad Bilal

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

Ultrasonic Pursuit Automobile

Phone Projects / Muhammad Bilal

We’ve implemented an autonomous pursuit vehicle capable of chasing a designated target using ultrasonic transmissions. The system is demonstrated by chasing a second, human-controlled, RC car. The pursuit unit is equipped with a 24kHz transmitter and two 40kHz receivers, while the target unit has a 24kHz receiver and a 40kHz transmitter. The target unit responds

Chiptune Mega Mega

Video - Camera - Imaging Projects / Muhammad Bilal

Introduction Our final project is a NES-style chiptune player that changes its playback tempo in response to heart rate measurements from the user. The chiptune player successfully generates four individual channels: pulse, triangle, noise, and delta modulation. After audio mixing through a hardware circuit, the resulting mono signal sounds as intended, with no waveform clipping

Real-Time Pitch Shifter.

Sound - Audio Projects / Muhammad Bilal

Introduction “A device that pitch-shifts voice in real time” For our final project, we attempted to implemented a real-time vocal pitch shifter. The system was designed to work as follows: a user speaks into a microphone, their vocals are processed using a pitch shifting algorithm, and the resulting signal is output through speakers. All of

Frequency Visualizer

LED Projects / Muhammad Bilal

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

Bioelectrical Body Fat Analyzer

Other Projects / Muhammad Bilal

Introduction For our final project, we have decided to use the microcontroller provided to make a device which would measure body fat percentage of one’s body. The basic principle behind this project is known as bioelectrical impedance analysis. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine
