Laser Pointer Switch using arduino

This instructable will detail how to make a switch that uses an arduino to sample light. When the light sample reaches a threshold it will trigger a relay that can be used to turn on/off a small appliance (light, radio, fan, etc...) The parts for this instructable can be ordered as a kit: Jameco Kit http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2209967_-1 Step 1: Review relay and prep ...

$1.50 Arduino TV Annoyer

Hey Arduino fans! Here is an 'ible for making a device that turns TVs on when you want them off, and off then you want them on! If you hide it in something inconspicuous, it would make a great April Fools joke or gag gift. And the best part is that the total parts cost is less than $1.50!! (Assuming that you already have an Arduino and the tools) This is a contest entry for the LED Contest with Elemental LE ...

Arduino R/C Lawnmower

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.  I have used this interface to control anything from basic LED's to Bipolar stepper m ...

RGB LED Rainbow Fader using an Arduino

Introducing the RainBoard: A simple RGB LED Rainbow fader using an Arduino Uno and a few simple components. Believe it or not, we will control 45-channels of RGB LEDs at 32 brightness levels using only 3 digital pins from the Arduino! How is this possible you ask? By using two magic concepts: Shift Registers, and Pulse-Width Modulation.  Some of the schematics/images may seem daunting, but if all instructio ...

Window Painting Robot (arduino, processing, accelerometer)

The idea for this project came from one of my favorite 'ibles: the polargraph. I loved the drawing style and thought how cool would it be to do this on the side of a building? Unfortunately the challenges to setting up such a large polargraph on a student budget pushed me to find an alternate solution, and thus started the window painting robot! This is a fairly simple robot that uses two neodymium magnets ...

Pixel Drop Ceiling using Arduino

In our living room we have a small patch of drop ceiling right in the middle of the room, basically a giant piece of duct tape to cover up bad carpentry. It was constantly getting water damage from what looks like a giant hole in the ceiling above the drop tiles. After roughly a year of living in the house I decided to take action. The Pixel Drop Ceiling was born. The Pixel Drop Ceiling is a Bluetooth, Ardu ...
