Programmable LED

Step 4 Assemble on a prototype board

If you like to test your circuit, a breadboard is very handy. You may assemble all parts without having to solder anything.

Hi Alex - this is a great project - I'm building my own right now - in fact I'm planning to build 25! Looking at your breadboard in the second picture it doesn't seem quite the same as your schematic in step 3 - for instance the LED are wired into pin 7 here and from pin 6 in the diagram. Can you help me out? Many thanks, Dave

Yeah, I was also just looking at that as well... I dont plan on making one but im always interested at looking at other developers projects... and I see alot of inconsistency's like for example: in source it says LED_BIT is 2, and commented he says thats PB2. when in the schematic the LED bit is clearly PB1. and the LDR is clearly connected to ADC2 witch is pin 3 in the source, but schematic tells a different tail... from what I can tell the image above is the correct placement, if you try to follow the schematic you will fail, its way off

Hi - I've made my fist one now - seems to be working well. This is my circuit diagram. Cheers, Dave

Hi Dave, I am sorry that my schematic was misleading. It was made after the actual project. Do you mind if I take yours to replace mine? And great that it works for you. Do you have a picture? Kind regards, Alex

Hi - certainly, very happy for you to use it. This is a photo of my version, the next one I try I'd like to go for something more organic. I'd like to end up with a whole crowd of them - all slightly different. Wondering about using a flex sensor instead of the LDR... I'll put all my photos on Flickr. Cheers, Dave

Hi Dave, schematic is replaced. And cool version. Keep posting pictures of the organic version. I would love to see them. Cheers, Alex

Just finished my second version... I'm posting them to flickr: http://www.flickr.com/photos/dave_chatting/tags/instructables/

Not very organic yet!

Cheers,
Dave

Hi Dave, the new one just looks great! Nice sculpture and nice picture. I like really it. Do you use the battery as mirror? Cheers, Alex

[dave_chatting]

Thanks! Yeah - the battery reflects the LED light at the moment. Wondering about uses it for the LDR instead. Dave

I love the whole idea of this little project, simple and neat! but one question after looking at this image, why do you have a socket on your breadboard? why not just connect the AVR to your breadboard... I do.

[alex_weber]

You are right. I haven't thought of it. X-) Regards, Alex

Is it just me or is that a couple of bread twist ties jumping the power rails in the 2nd breadboard picture. If it is... kudos on a unique recycling job.
