This project brings back the old time Analog VU Meter, with the added functionality of a neat looking clock! When you turn off your music the meters automatically swing into to clock mode. Behind it all is the popular and easy to use Arduino. This is my submission for the Make-to-Learn Youth Contest: What did […]
Jeopardy style quiz games are favorites for creating excitement and educational instruction at the same time. Teachers, summer camp counselors, and even industry educators find this type of game to help generate interest and involvement from the participants. The idea behind the game is simple, but sometimes finding a device that will perform the “first
Quiz Game Controller using “Lights and Sounds Buzzers” and Arduino Continue Reading
The easiest way to connect an audio signal to your arduino, is to build a simple 3 components (2 resistors plus cap) circuitry shown on the first drawings on right side. Disadvantage: there is no amplifier, and consequently sensitivity would be low, hardly enough to work with headphones jack output. For low level signals, like
The idea of using triangulation for distance measurements is well known since Pythagorean time, when his brilliant formula become available for mathematicians. What is new in this design, is lasers power control via “blooming” effect of CMOS camera. Here this “negative” effect was put to work instead of ADC. No need high price “no-blooming” camera!
O’K, after having some fun with stereo version of the VU meter I described in my previous blog-post, now it’s time to do a serious stuff. Studio grade VU meter !!! 24 steps, equally spaced every 3 dB, covering Extra wide Dynamic Range from -63 up to +6 dB. Single (mono) channel this time, no messing around,
Audio VU meter with Extra wide Dynamic Range 69 dB using Arduino Continue Reading
The basic idea was to create color organ / spectrum analyzer on arduino board, trying to minimize quantity of external components, like analog filters, LED display drivers, etc. Spend a lot of time in search on internet I was able to find only two ! project , which implemented FFT in order to solve a
Spectrum Analyzer, Arduino project with FFT algorithm Continue Reading
Project by CU Boulder Thinks That Think students: Michelle Bourgeois, Charles Dietrich, and Ben Link Imagine having a safe in which the combo is any small object of your choosing. Perhaps it’s your favorite coffee mug, or a bat man figurine. This project is based on this idea, using the weight and placement of your
Hey everyone, I finally finished my touch panel for my bedroom wall and am here to show you how i made it. Unfortunately its not installed in my wall yet as I might be moving and don’t want to make anymore holes in my walls, but its coming with me and has already proven itself
This project is a collaboration between idesigner4 and bhasudha(me), students in the Fall 2012 course Things That Think (CSCI 7000) at The University of Colorado – Boulder. The story of our bug-catching spider automaton goes like this: A giant evil spider resides in a big web. One day an unfortunate lady bug gets trapped in
Bug-Catching Spider in Web using Arduino Part 2 Continue Reading
What this is: This instructable will show you how to make your Arduino into an R/C interface that you can use for just about anything requiring remote control. I will also show you how I built an R/C lawnmower using my Arduino, a cheap R/C transmitter and receiver pair, and a couple of electric-wheelchair motors from Ebay.
