Persistence of Vision (POV) Wands are a fun way to create interesting long exposure photographs and light displays. The wand consists of a single row of LEDs controlled by an Arduino Uno. When the wand is turned on it appears to be flickering in a random pattern, but if you move it quickly back and

first what youll notice my grammer isnt the best 🙂 ok what youll need: 1 transister/mosfet that can handle the current for the water gun motor, this is the one i used – http://www.sparkfun.com/products/10213 – then a diode, i used this one – http://www.sparkfun.com/products/8589 – then a 10k ohm resistor, then a PIR, i didnt use this one but it should

My brother posted a video about this on facebook almost a year ago. Some old floppy drives playing Bach’s masterpiece Toccata & Fugue and it got me really interested. So I read about it when the author posted a how-to on his blog and did a couple of tweaking using SammyIAm’s Musical Floppy program when the project gained a

Who wants grinning faces and candles when you can have an interactive pumpkin this Halloween? Play your favorite block-stacking game on an 8×16 grid carved into the face of the gourd, lit by LEDs and using the stem as a controller. This is a moderately advanced project and requires experience soldering and programming in the

In this Instructable we will explain how infrared signals are used by a remote to control a toy or device, then show how a simple circuit can be added to an Arduino to operate the same device through free, Open Source software. This document is part of a series covering the Puzzlebox Orbit, a brain-controlled helicopter that features

There are several good Jeopardy/Game Show lockout buttons/buzzers, but none incorporate the timing rules of Jeopardy. I am learning about the Arduino and I thought that this would be a great project to practice with. The rules include a question reading period with no timeout to reading the question. During this period, any player who

Let’s put together a pixel strip with an HL1606, an Arduino UNO and the Spectrum Shield to build a seven bands “large” Spectrum Analyzer of simple construction. The Strip used uses the HL1606 controller to allow direct management of each of the LEDs. The chip runs two RGB groups and has 4-pin for input/output. The
