Fading LED Project
« on: January 29, 2010, 04:47:53 PM »
EDIT: I have my Breadboards

But here's a few ways to go at it to fade LEDs:
Schematics will be Posted Later for you people.

X Option 1 "The easy way out":
Put a RC circuit on paralell with the LED.
As the power source is removed, the charge stored in the capacitor is slowly bled through the LED.

Cost Approx: $4-$6
Most Expensive Component: Capacitors

Schematic:



================================================

X Option 2 "PICs":
Get a PIC and program it to fade, but most people don't have the time and ethic to do this.
Pretty Reliable, your best bet here to conserve battery life.

Cost Approx: $2-$5
Most Expensive component: The PIC

Schematic:











================================================

X Option 3 "D/A Converter":
a 4017B Chip can be used as a digital to analog converter to fade the LED with resistors to comply with 10 different variations of resistance to suit your needs to fade an LED with smooth clock pulses that are easily controlled by a 555 timer.

This way is Semi Cost effective, sometimes reliable, but not the most compact design. (too many resistors) and Most importantly its possible to be Multi-functional and will drive 10 Separate LEDs

Cost Approx: $4-$10
Most Expensive Component: Resistors

PART 2 IN ACTION:

================================================

X Option 4 "Delayed Pulse Generator":
Currently I'm Working on this one. It is a Very Cost effective and good for beginners. Only requires 2 of the notorious 555 Timers and a few resistors and 4 caps.

Cost Approx: $3-$12
Most Expensive Component: 556 Dual Timer or 4017 Decade LED Driver Counter

FOOKz You Are a legend I'm Gonna Try One Of These to get me back into electronics and I'm sure When/If You Make A Tut It will be top Notch

SWEET!! Option 3 "D/A Converter":
 
Finally been waiting for the vid for the mod..looks like i can create a KIT look..if i didnt confused anyone KIT is the car from the Origional knight rider show from  the 80's...i was wondering if i can also do one of this on a PC..And I know the perfict area to add that to my PC case.. right on the door... so i can watch the Arua of blue lights climbing up and down XD 
...emo freak out! >.< ........

random is fun

Hey people, im here to answer any question you want me to about these projects. I am diligent enough to make more videos for more in depth explanations if you need one.

Thanks Lobo you aint too bad yourself ive seen stuff you've done.  :tup:
