Very cooool! I like the "tong" at 1:40 smiley-wink

Discovered this today; I'm deeply impressed! Very nice work. Perhaps some time in the future I will build such a "monster" too smiley-wink but there are a lot other projects in the queue.

James, many thanks for the explanation and the link. I'm new to MacOS, so now I've learned someting.

Many thanks. I can confirm, that it works.  smiley-grin

Just to add another user smiley-wink. Same problem here: OS X 10.8.3. Arduino 1.0.4 is installable without problems, but 1.0.5 shows the damage message.

6  Using Arduino / LEDs and Multiplexing / lolshield: Text does not work on: January 25, 2013, 12:45:44 pm
Hi all,

I just gambled with my new lolshield. The usual demos ran fine; then I wanted to display some text, but the shield remained dark. So I stripped down the code to display only one letter:

Code:
#include "Charliplexing.h"
#include "Font.h"
#include "Arduino.h"

void setup ()
{
    LedSign::Init ();
}

void loop ()
{
    LedSign::Clear ();
    delay (500);
    LedSign::Set (4, 4, true);
    delay (500);
    Font::Draw ('A', 0, 0);
    delay (500);
}

I expected that the letter 'A' blinks, but again the shield remained dark. If I delete the Font::Draw command, then the LED at (4,4) blinks as expected.

What am I missing here? (BTW: I'm using the IDE 1.0.1)

best regards
Andreas

Many thanks for all your replies! I think I will try a PIR or a photoresistor. Because I have tons of other things to do before christmas I move this project to the next year. Perhaps a rabbit with red glowing eyes for easter (in Germany the "easter rabbit" hides chocolate for the children on easter morning  smiley).

best regards and merry christmas

Hi *,

OK - for clarification (sorry, it seems that my english got a little bit rusty smiley-kiss)

I have attached an image of our typical office door (hope it works from my tablet  smiley) You can see the hallway through the window. I will put the device (perhaps a sort of star or snowflake with 24 LEDs or so) onto the inside of the window. If a colleague walks down the hallway the LEDs shall start blinking (this is the easy part, I've prepared such a thing with shiftregisters). But alas I cannot install anything on the other side of the hallway (that would lead to trouble with the boss :-().

I've thought about a camera, but it seems a little overkill for this little project.

thanks to all and best regards
Andreas

Hi *,

for a christmas project I need some advice. (OK - christmas 2013 - it's too late for this year  smiley-roll) Some background: in our office we have small windows next to the doors, as high as the door and 25 cm wide. I want to create some blinking stuff, which shall start, when someone passes. An ultrasonic sensor (srf04 or so) will not work, but what's about an IR sensor? Does it work through glass?

best regards

Insert an additional delimiter, e.g.
 
D,368,175,D,367,175,D,368,175,D,368,175,D,368,175,D,368,175,
Etc.

How did you take the photos (without burning your eyes  smiley-cool)

I've tried to see the eclipse in germany in 1999, but I got wet - rainy, clouds, and no sun  smiley-sad)

13  Using Arduino / Programming Questions / Re: LED Chasing Lights Progamming on: May 25, 2012, 06:21:36 am
But what is byte j? Are you creating and naming a byte with that declaration or is byte j something that already exists that you are calling upon?  

Look here?

Code:
Description

A byte stores an 8-bit unsigned number, from 0 to 255.


It's a good idea to look into the reference from time to time  smiley-wink smiley-wink smiley-wink

This construction declares a variable named "j", which can hold values between 0 and 255 (incl.).

In volume 2 of "Donald E. Knuth, The Art of Computer Programming" is a whole chapter about creating random numbers. Perhaps this will help you.

I've created the version 2 of my evil spider by replacing the LED in the head with two LEDs in the eyes. You can see a video, the source code and two photos on my blog. I didn't want to put the close-up photos here, where perhaps arachnophobic people stumble over them  smiley (the photos are at the end of the post, so you can see the video and the source code without being too feared).

best regards
Andreas
