Functional Lit Costume Goggles for Mr Freeze

Egads!  LED Goggles you can see through (surprisingly well, too)!  They pulse subtly, making them so cold and dehumanizing. They were totally perfect for the character I was going after - Mr Freeze.  It was my first time really playing with LEDs and Arduinos, so it was a good learning curve hugely aided by the wonderful Instructables community.  The biggest lesson here for me (as with virtually every projec ...

Basic Arduino Tutorials : 01 Blinking LED

In this instructable, I'm going to show you how to make a simple circuit/code with an arduino, which will make an LED connected to it flash from off to on, with 1-second intervals, as shown below. This is a very easy, basic idea, however it leads to many more complicated codes and circuits. Attaching the Power Cables and resistor to the Breadboard Firstly you will need to plug one end of a wire into the '5v ...

Phone Controlled Mood Lighting

Dorm rooms are notorious for their dreadful lighting, so I wanted to make a cool alternative light source for my room at school. I made it phone controlled so there would be an easy and wireless way to change the color of the lighting. The lighting consists of Tricolor LED Strips and are controlled by a phone through an app. The app is able communicate with the Arduino via bluetooth by using the Seeed Bluet ...

Better LED as light sensor

As a result of the questions from lekirst  on this ible of my hand: LED-as-lightsensor-on-the-arduino/ and the cleaner code made by hansc44 at:  Arduino-Use-LED-as-a-light-sensor/ it was time to come with a better Ible. So here it is. (I didn't solve lekirst's problems yet so she probably is open for suggestions) What is the idea? You might know that a LED emits light when you put the right amount of volts ...

Frameless Laser Harp

We are a generation that love sound and light – can’t do without them really. Our most preferred time of day is night, or what we would call evening. We are particularly well acquainted with technology; doesn’t hurt these days. Our prerequisite for everything is that it be ‘cool’. Put it all together and in a stroke of brilliance, and a little help from our friend the internet, we have the ideal solution – ...

5X5 dot matrix on Arduino

With this you just type the text you want on your computer and your 5x5 dot matrix shows the message. Used: ~25 leds ~Arduino uno ~5x 100ohm resistor ~and a bit of skripting It took me a while to figure this all out but in the end it was quite rewarding. not really practical though. :) Enjoy. Plz comment and let me know what you think. Step 1: You wil need.. 25 leds Breadboard Arduino-  have the uno- Sharp ...

Laser Triggered Countdown

This is a simple arduino based project that consists of a laser tripwire that, when triggered, will begin a countdown sequence on red, orange and green LEDs. I designed this to be an easy project for someone learning how arduinos work (like me). This is my first instructable so please bare with me :) (I'll apologies in advance the picture quality, my phone's camera isn't too great) Let's Go! Step 1: Materia ...

Hidden light control using Arduino

I’ve bought recently some cheap dual axis magnetic sensors at SureElectronics (http://www.sureelectronics.net/goods.php?id=944), I’ve tried first to use them as straight compass. Annoying problem : it’s impossible to accurately compensate the tilt of the sensor without using a gyro sensor. On the other end, if you stay on the same horizontal plan, the measures are pretty accurate even if you consider their ...

Rainbowduino Sign using Arduino

The Rainbowduino is a variant of the Arduino and among other things is capable of driving an 8x8 RGB LED matrix. I had just finished a backyard re-model and was in need of an entrance sign. Step 1: Carving and Painting the Sign I had recently acquired a CarveWright CNC wood carving machine. It's a pretty nice piece of equipment and comes with some pretty easy to use design software. Then you just print out ...

Potentiometer or variable resistor control LED Code

The if() statement is the most basic of all programming control structures. It allows you to make something happen or not depending on whether a given condition is true or not. It looks like this: if (someCondition) { // do stuff if the condition is true } [Get Code] There is a common variation called if-else that looks like this: if (someCondition) { // do stuff if the condition is true } else { // do stuf ...
