Simple Binary Clock for Arduino

03/03/2010

Binary clock using Arduino.



If someone wants to make the circuit all it is is each LED is connected to a digital pin from 1-13, and 2 tact switches connected to analog 0 and 5. The LED numbers are the right most column bottom LED is LED 1 and counts up. The next column over would be LED 5 and counts up and so on.

here’s the code.

Build your own Arduinome

01/03/2010

Super easy instructions for building yourself an Arduino Based Monome. Nice renewal of the site.
Cool

Babuinobot Project

25/02/2010

Isn’t an Arduino visual programming tool for kids (and noobs) everybody’s dream?
Well, by reading this documentation. All you have to do is downloading the software and go through the instructions.

Loving these picture of youngsters interacting with PC & technologies

Poorman’s oscilloscope (with Arduino + Processing) AND Arduinoscope

25/02/2010

If you are looking for visual representation of an analog signal using Arduino and Processing then you might download these skecthes.

Oscilloscope.pde 1.88 KB
oscilloscope.h 2.92 KB

The if you are looking for a more rieliable and debugged sketch / program doing preatty much the same thing, then the Arduinoscope if for you.
Try both. Customize. Enjoy.

Arduino Helicopter Game

25/02/2010

Wow. Really interesting helicopter game with several nice feautures.

Specifications:

  • just under 8kb (so it should fit a cheap Atmega-8)
  • Speed and block size grow
  • Still a little glitchy, weird artifacts, is anyone able to fix them?
  • Day and Night mode, hold the button when game over for night mode, gentle press for day
  • Score build in, post your highscore in the comments ;)

To play:

  • Connect a KS0108 LCD as described in the library’s page
  • Connect a button with a pull-down resistor to pin 12
  • Make sure the KS0108 library is available
  • Upload the sketch
  • Enjoy!

Download it here…

nice job Dave.

the sbx 16x4x3 (SkinnerBox StepSequencer)

24/02/2010

Another, interesting arduino based step sequencer.
Very well documented.
People are just harvesting hardly!

as we want to connect 20 buttons, 2 potentiometers
and a 12 scale mode-selector, we need a total of 34 inputs. additionally, we want to control 20 led´s, so we need 20 digital outputs. the arduino has 6 analog inputs and 14 digital inputs/outputs, which is obviously not enough, so we are going to use five
4051 analog multiplexers to multiply our analog inputs and create a total of 40 inputs, and three 595 shift registers to multiply our digital outputs and create a total of 24 outputs.

Code Ready. Wow.

Arduino Pachube Library

24/02/2010

As I read on this blog post by Jose Anes, he has been working on a while on the Arduino > Ethernet shield > Pachube communication, to achieve “a Pachube manual update client on the arduino that pushes EEML XML format to Pachube directly, without a PC in the middle”.



If someone has a better library, please let me know where to find it.  Here is a link to the code I am using to accomplish this purpose.  So far it is working well enough.  Some interesting points:
  • I had to print directly to the stream (ethernet in or out), because creating an EEML XML string was too much for the small memory of the Arduino.  Direct writing as a stream solves that.
  • I still want to avoid the reset every time it uploads to pachube (took that from the pachube CSV example).

The code: 20100218-pachube
