Arduino Double Dice Jewelry Box w/ Secret Switch

This was a fun project. Push the red button, watch the dice " ROLL " then stop on a random roll most every time. The hart of this game is the ATMEL ATmega328P on a stand alone board. Powered by 4 AA NiMD batteries. Can you find the SECRET SWITCH in the main picture? Where is the SECRET SWITCH? The first person that answers the TEST question correctly will win a PRO 3 month subscription to Instructables. Thi ...

Heat-Seeking Desk Fan (using Arduino)

Summary: The following is a step by step guide on how to make a Heat-Seeking Desk Fan from an Arduino microcontroller, a computer fan, a servo, and an infrared temperature sensor. The device scans the room periodically, automatically pointing itself in the hottest direction (ideally towards a person). This is a working proof-of-concept model, but it could be easily scaled up should the investment seem worth ...

Arduino Lilypad Slipper Automatic Foot Massager

I made a little automatic slipper foot massager with the Lilypad Arduino and some of the Lilypad Vibe Boards for the actual massager. The sensor it uses is a Lilypad Accelerometer that I'm only using as a basic tilt sensor. Essentially it detects when the slipper is in a more vertical position (like when you would kick your feet up to relax) and then turns on the motors. When the slipper is in a more horizo ...

Holiday Dreidel Light Display for Roof using Arduino

This Instructable details how to build a holiday dreidel display for your roof. It uses coat hanger wire, rope light, and an Arduino controller to control a fading demo mode and a "spin" mode. In the demo mode, the symbols fade in and out, going from one to another. In "spin" mode, the symbols flash in sequence with an increasing delay between symbols until the dreidel "stops" on one and flashes. The spin f ...

Arduino Personal Soundtrack Hoodie

This was inspired by Raj's personal soundtrack shirt in Big Bang Theory S3, E16, "The Excelsior Acquisition". You can now buy them online but it's much more fun to make your own and it's possible now that buttons designed for use in electronic clothing are available from Connectedwear. Nine of the buttons on the Connectedwear keypad sewn into the hoodie's arms each play a given sound or tune and the tenth a ...

Star Jar Geiger counter triggered LED decoration using Arduino

This instructable builds on top of the Geiger counter triggered LED decorations I made last year. This version powers the Geiger counter from the Arduino (itself now powered from a mains adaptor, so I no longer need to keep feeding them batteries) and the LEDs now fade in and out for a more gentle effect. What you'll need: A Geiger counter with pulse output (I'm using the Gieger counter from MightyOhm) A fe ...

The Motivational Moody Workout T-Shirt using an Arduino

I call this project "The Motivational Moody Workout T-Shirt" . Basically what I wanted to do was a t-shirt that makes you want to get out in the open and work out. To make that work, I sewed a LilyPad arduino onto a t-shirt and powered it with a solar panel. Then I connected a bunch blue LEDs in smiley face patterns to the LilyPad board and finally a ball tilt sensor. So for it to work you have to be outsid ...
