Arduino in HighDef Macro Pictures

Today I was having fun with a MacroLenses and decided to take some pictures of my Arduino Uno board, I got quite happy with the results that I am using them as wallpaper, and I decided to share with you.

You can find the original file ≈ 15mb, also 1920×1200, 1680×1050 and 1280×800.

Dotklok + LM35 Temperature Sensor

I got my Dotklok up and running some days ago, I am really enjoying it on my room.
But I want to do more with it. Too bad right now I don’t have much time to play with electronics and build cool things.

Anyway, today I decided to spend some time learning the Dotklok’s code and add a temperature sensor to it. The result was really cool, and now I am sharing the bit of code I added to the clock.

Arduino + Sound Sensor

I got a sound sensor on Ebay some days ago, and decided to give it a try!
Really simple, just made a code to light up the led when the volume was higher the ambient sound.

Just for fun!

Using Arduino to calculate Quadratic function

This is a simple and quick code I made for teach variables with arduino programming,
where we enter the variable numbers a, b, c in

and we get the answer using the Serial Monitor..

I won’t get in details about this code, it’s quite straightforward. But if you have any question, just ask!

Moodlamp Mod

I made some modifications in one of my projects, my moodlamp, where I mounted it in a CTRL huge key.

I’m planning on releasing all the project as Open Hardware/Source, but due my lack time, it’s not on my website yet!
Would you like to take a look at this project??

My DotKlok

Hey, I got so exited about the DotKlok that I decided to build my own! As it’s quite difficult to buy one from here (I live in Florianópolis – Brazil), and to pay U$150 for the Kit wouldn’t work for me… So I want to build a good looking clock for my room, which I only have my computer and mobile as clock.

First of all, I needed to buy the 24×16 Led Display from Sure Electronics, which I found for a good price at eBay (little cheaper then buying from the Website).

Femtoduino: an ultrasmall arduino board

This is amazing, perfect for those times when your have to create another board just to hold the atmega µC. I am looking forward to use this tiny board in some project in a near future. Congrats to Varesano for the project.

You can check his project HERE.

Arduino-Based Digital Clock

Wow, this is amazing! DOTKLOK is an open-source, hackable, Arduino-based digital clock that displays a series of unique time-telling animations.

DOTKLOK: Game Time from The Latest Artists on Vimeo.

DOTKLOK is an open-source, hackable, Arduino-based digital clock that displays a series of unique time-telling animations. The passing of time is depicted with numbers and abstract/geometric patterns such as Morse code and minimal analog clock faces, and includes animations inspired by classic video games such as Pong, Tetris, Pacman, and Space Invaders.

You can buy the kit for U$150.00 and it assembled for U$200.00
for me… I think I will build one, hell yeah I’m going to build one, just love it!!!

You can check more information from dotklok’s website.

Arduino The Documentary (2010)

I know I haven’t posted much things lately, but there’s more to come in a near future!! You will like it! But for now, you HAVE to watch this amazing documentary about the Arduino Board and it’s story!

Arduino PWM & Oscilloscope

Having fun with Arduino PWM & Oscilloscope and trying to understand some more

Here are some links if you want to know more at Wikipedia and Arduino Website
