Froggy World 5 The Coffee Gripper

In Froggy World, the amusement park for adventurous plastic frogs, it became necessary to to move the frog from a train car back to the catapult.  Because I couldn't know whether the frog would be upright or sideways--and in what orientation--the gripper was a challenge. I read about the "coffee gripper" developed at Cornell and used that technique for transporting the frog. In the video, I cut out the "20 ...

Big Spectrum Analyzer with Arduino

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 serial communication protocol allows input to output passage whenever the chip receives new da ...

Capacitive touch Mood light using Arduino

This instructable is a quick write-up of my experience creating a multifunctional moodlight. Some basic knowledge of electronic circuits is expected. The project has not yet finished, some adding functionality  and tweaking has to be done but it is already functional. If you guys are enthousiast about this instructable I will update it. At the heart of the system is an Arduino. It will process the input fro ...

Persistence of Vision Wand using Arduino

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 forth, you will see text or an image appear.  This wand project is incredibly customizable, I've included al ...

Batgirl Birkin Bag

What a girl wants. What a girl needs.  What's more exclusive and has more cachet than scoring a Birkin bag? Pow!!! A Batgirl Birkin bag! Holey Haute Couture, Batman! Yes, you too can knock off a version of this famous bag.  Okay, even mine started out as a knockoff so you ain't doing anything iffy by copying another knockoff. No need to worry about the caped crusaders coming after your Fn a... wait, maybe t ...

Internet Devices for Home Automation using Arduino

This instructable shows the principles involved in making devices to control home automation over the internet. We're going to construct a device (or several of them), that talk to each other over the internet to control lights, motors for curtains/blinds, power sockets etc. In contrast to devices controlled from a web browser or phone, these are designed to be simple, Arduino based devices that are capable ...

Daft Punk Coffee Table 5×5 LED Matrix using an Arduino

Yes, I know this has been done before, but I wanted to build my own, using as few parts as possible.  I built this as a table top or wall mount model, but it can be scaled up to make a coffee table.  I built it as a study for a more ambitious project, which will be an 8x8 RGB coffee table.  In designing this project, I wanted to keep the part count and cost as low as possible, and also to design the softwar ...

Pet Curfew: An Arduino Controlled Pet Door

The Problem: You want to restrict the time when your pet is allowed to go outside. This could be because the neighborhood is not safe for your cat or small dog at night (marauding coyotes comes to mind). But you would like your pet to be able to come in at any time. The Solution: Pet Curfew, an arduino controlled pet door, with real time clock, cat status led light and servo latch. Video here. Step 1: You w ...

Build a transistor circuit board for controlling Air Conditioner remote control with Arduino

I was supporting a group of student on their graduation project. One of the difficulties they faced was on controlling an A/C unit with Arduino microcontroller. The first experiment we tried to work it out was by record the A/C remote control beam signal for each needed button by using the IRrecvDump code with IRremote library for Arduino (https://github.com/shirriff/Arduino-IRremote). Then, use these signa ...

Twitter Mood Light using an Arduino

How's the world feeling right now? This box tells you. Powered by: an Arduino, a WiFly wireless module, an RGB LED, Twitter.com and a 9v battery. I’m a news junkie. I want to know everything that is going on in the world as soon as it happens. I want to wake up and know immediately if something big has happened overnight. However, I’m an extraordinarily busy man; I don’t have time to read news feeds; readin ...
