Programmable LED

Step 6 Soldering

If your circuit works on the breadboard you can solder it.

This can be done on a PCB (printed cicuit board), on a prototype board or even without a board. I decided to do it without as the circuit consist only of a few components.

If you are not familiar with soldering, I recommend that you search for a soldering tutorial first.

My soldering skills are a bit rusty but I think you get the idea.

I hope you enjoyed it.

I love this !
Great ideas !
The freestyle assembly and minimal parts make it a less is more thing.
Thinking it might be interesting to maybe use a few more parts to make it look like a man or robot or something.

Can this only blink on and off, or can it fade also?  Such as if you program it using a light with a dimmer switch.  And does anywhere sell just the chip (not a full kit) with the program already on it?  When you remove the LDR, does the chip remember the last sequence entered from then on, even if the battery goes dead and has to be replaced?

Yes, you could make it fading. For that you should google for PWM (pulse width modulation).

The recorded sequence is stored in RAM, so it would be lost if the battery goes dead. But you could store the sequence in EEPROM.

Very nice one! Funky gadget!

it's a very good project! Congratulations! i can't build it, because i have anything. i'll build it later :(

"i can't build it, because i have anything" ?

Seems like a small tweak to the code could insert a "bright dark bright" sequence into a random location in the playback. Then you could put a few of these in a dark room and they would "learn from each other." It would be like a living art display. That thing looks a bit menacing. I hope it doesn't decide that we should be entertaining it. I'd sure hate to see such a cool project turn into SkyNet.

Excellent project - clever idea to make it 'learn'. Now if we combine this with the resistor man sculpture... A robot that winks back at you!
