This project aims to implement an electronic tuner which is able to analyze sound samples and display the notes contained in the sound. It utilizes a PIC32 microcontroller, a microphone circuit, and a TFT LCD to achieve that purpose. The intuition of making this project came from the musical experiences of both of us. We […]

This project is an extension of a number of musical projects (Happy Birthday and It’s a Small World) and puts 11 melodies into a single design. It’s called EVOLUTION. From the previous projects we learnt a lot about producing a tune. The first thing we learnt: it takes a lot of memory. Each note needs

This project has been developed due to a request from Mr Moshweunyane ([email protected]). He asked for a circuit that would count up when someone entered a lift and count down when someone exited, using two infra-red sensors. All we had to do was take the 2-digit up/down counter and add two optical sensors. These sensors

Introduction This project implements a real-time audio spectrum analyser using a PIC18F4550 8-bit microcontroller. The spectrum frequency analysis is performed by a highly optimised 16-bit Fast Fourier Transformation (FFT) routine coded entirely in C. The output from the FFT is displayed using a 128×64 graphical LCD to allow a real-time view of an audio signal.

As explained earlier, a seven segment interfaced with PIC uses almost an entire port (minimum 7 pins) to display a value. But a real time application, like watch, calculator etc., usually requires at least 3-4 seven segments. In such a case it is not advisable to use a port of the controller for each seven

Introduction The purpose of this final project is to implement a microcontroller-based platform stabilizer. The major components of the platform stabilizer is an Inertial Measurement Unit (IMU) and two 180 degree rotation servos. The IMU uses a combination of a 3-axis accelerometer and a 3-axis gyroscope to provide measurements of the platform’s motion and angular

Description This project is a crystal controlled precision timer providing accurate delays from 1 second to 15 hours 45 minutes. The timer delay is set using a 10-way DIP switch. The timer is started by pressing a switch on the main PCB or from an external switch connected via the terminal block connection. A second

Introduction By measuring brain activity using electrodes and an amplifier circuit, electroencephalograms (EEGs) are at the intersection of electrical engineering and neuroscience. By using signal processing techniques, we can examine the effects of external stimulation, such as music and meditation, on brain waves. We primarily examined alpha and beta brain waves in our EEG. While
Description This project came about because I have three motorbikes and being a bit of a fair weather biker they don’t get used much over the winter months. I have an OptiMate™ 4 charger that I connect to the bikes but this needs me to manually swap it from one bike to the next and

The 3rd harmonic distortion meter has been designed for measuring the quality of AC supply. The meter is built with a PIC18F2550 project board and the full wave rectifier front-end circuit. The AC power line, 220VAC is measured through the step down isolation transformer. The input signal to the 10-bit ADC is full wave rectified.
