Graphical LCD Oscilloscope using ATmega16Microcontroller

LCD Projects / Ibrar Ayyub

Introduction The popularity of microcontrollers is on the rise, thanks to their compact size and impressive capabilities. Embedded systems are being constructed around microcontrollers and peripheral devices [3]. An oscilloscope is frequently employed to observe the waveform of an electrical analog signal, typically representing voltage, time, and frequency. Parameters such as peak-to-peak voltage, frequency of

Master the Art of Servo Motor Control Using AVR ATmega16

Motor Projects / Ibrar Ayyub

Overview of Servo Motor A servo motor is an electrically powered actuator that allows for precise control of angular rotation. It provides controlled movement important for applications like robotic arms that require precision. The rotation angle is dictated by a PWM (pulse-width modulation) signal sent to the motor. Varying the width of the PWM pulses

7-Segment Display Interfacing with AVR ATmega16/ATmega32

LED Projects / Ibrar Ayyub

7-segment displays comprise 8 LED elements – 7 linear segments that form numerals, plus a circular dot. Numbers 0-9 and some letters (A, C, D, E, F, H, L, O, P, U) are represented using combinations of the 7 lines. The dot creates decimals. Each element connects to a dedicated pin, allowing individual control. Pins

BOXING TRAINING

Other Projects / Muhammad Bilal

INTRODUCTION In the modern American classic, Rocky IV, Ivan Drago (portrayed by Dolph Lundgren) is shown utilizing a then-futuristic electronic punch meter (in addition to anabolic steroids) in his quest to triumph over Rocky in one of the Cold War’s only face to face confrontations. While we dispensed with the communist symbolism (and controlled substances)

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

REAL-TIME SCROLLING SPECTROGRAM

Other Projects / Muhammad Bilal

INTRODUCTION This project implements a real-time scrolling spectrogram-style visualization of an audio signal. We successfully displayed the frequency spectrum content in real time using a 4-bit grayscale scrolling display on any NTSC television. The frequency spectrum of an audio line-in input or mic input is calculated and displayed in real time using two ATmega1284 microcontrollers

LINE FOLLOWING AND OBSTACLE AVOIDING CAR

Car Projects / Muhammad Bilal

1.1 Introduction Line following car is a system that traces black lines on white surfaces. There arevarious sensing methods available to sense these lines. The choice of these schemesdepends upon sensing accuracy and required flexibility. In my project, I have used 6 TxLEDs and 6 IR sensors to accurately calculate the position of the robot
