Introduction The webpage describes the development of an Audio Spectrum Analyzer based on PIC32 microcontroller with the following features: Real time speech signal acquisition Spectrum and spectrograph visualization of Mel Frequency bands Serial interface for forwarding Mel Frequency Band Power Spectrum coefficients Recording and playback of speech signal using serial RAM Spectrum Visualization on PC […]
Introduction In this project, we implemented a two-degree-of-freedom ball balancing platform using a resistive touchscreen, two servo motors, and PID control. We used a PIC32 microcontroller to read position data from the touchscreen and drive the servos, adjusting the platform’s angle. We tuned the system to balance a 1 inch diameter steel ball using a

Introduction and High-Level Design When we were brainstorming ideas, each one of us had different interests. Max wanted to do an audio-related project as he is working for McIntosh, a company that designs and manufactures handcrafted legendary home audio systems. Ben wanted to make something that would be highly visually appealing. Alek wanted to take
Introduction Audio effects are used in nearly every recorded and live song across genres, whether its reverb being added to a vocalist or noise being filtered from a drum track. When used with guitars, they’re so ubiquitous that the interesting tones they create are often already associated with the instrument (like distortion), although they can

How about a method of automatic identification through radio signals that can bring you security and control the access of people to a certain location? This is possible through radio frequency identification or RFID from the English Radio Frequency Identification. And it is the assembly of this system that I am going to teach you

WHAT IS PWM? PWM STANDS FOR PULSE WIDTH MODULATION is a technique by which width of the pulse is varied. To understand this concept clearly consider a clock pulse or any square wave signal it has 50% duty cycle that means Ton and Toff period is same, The total duration for which the signal was high and

For some of my PIC projects I need a serial (RS232) interface to print some messages on the screen of my computer. I still have a desktop computer that has one RS232 interface but nowadays most computers have a USB interface instead. You can buy devices that convert – TTL – RS232 signals to USB
Most high-end modern vehicles come with keyless car Alarm or PKE:as the name says in the key less car you do not have to use any key to unlock/lock the doors neither start the car engine. to unlock or lock the doors the driver just presses on the small black button mounted at the door

This project creates a RGB LED lit love heart which is controlled by a PIC12F683 microcontroller. I designed the project as a gift for my wife on our 15th wedding anniversary (since she puts up with my addiction to electronics I thought she deserved something in return!). The love heart is made from a 200x150x6mm
