“All waveforms, no matter what you scribble or observe in the universe, are actually just the sum of simple sinusoids of different frequencies.” Hi, I am just refreshing the basics of fourier transform. I am not an expert. Now I did a small audio spectrum analyzer(0 – 10KHz) on a 16×2 character lcd using an […]

This project is used to measure the distance using ultrasonic sensors. The ultrasonic signal passes through the atmosphere to a barrier, which we want to measure the distance. Part of this signal is reflected and travels back to the receiver. The time delay between sending and receiving signals are then determined by distance barriers. The device was designed

This Instructable will be about designing a music player from using various building blocks. You will understand the communication between the microcontroller, memory, computer, LCD display, RTC, IR remote, and the music file decoder. I will try my best to to teach you in a way so that you can design your own projects using the

This Speaking Calculator project is an interesting device built just by three chips that can be very useful to blind people. The system has four basic operations (addition, subtraction, multiplication and division), and the functions: clear all, change of sign (+/-), inverse (1/x), square root (v), pi number (p), add with memory (M+) and read from memory

This is an evaluation use of a small graphics LCD module. Last summer, SG12232C graphic LCD module has been sold sold for 1500 Yens from Akizuki Denshi and I bought it. However I could not find good application for the LCD module and it was going to go to junk box 🙂 so that I tried to use the

History I decided to do this project for several reasons: first I like music, second I have a huge collection of MP3, and third I wanted to be able to play them anytime in my living room. I began the project with one major restriction, the printed circuit board of MP3 player MUST be single

Introduction Every group wants their final project to be something that will be remembered long after they’re gone. Some do highly sophisticated and complex projects that entail upwards of a hundred hours to complete. Yet others go out of their way to develop something ‘cool’ and ‘fun’. Luke and I decided that we wanted to

Introduction Our final project is a music synthesizer that is capable of producing a variety of musical sounds, by modify, the attack, decay, sustain, release times, and applying special effects such as a low pass filter or a halftone shifter. Our original interest for this project came from one of our TA’s (Idan Beck) while

Introduction This project is implemented with a glove, resembling a conducting baton that analyzes gestures and interprets them into musical elements. Der Kapellmeister is a simple tool that tests a user’s ability in basic conducting, using a real conducting baton. As a user performs a gesture, the tool will display the tempo, time signature, and beat
