I found some Surface Mount LED's that would be small enough. The voltage I dont really know about.
Code:
The LED information is this.
| If | Iv | Vf |
| (mA) | (mcd) | typ/max |
|--------|--------|---------|
| 20 | 17.0 | 1.7/2.0 |
What type of battery am I looking at to run 20 of those? It is not 2.0*20 is it? I cant find any info on building a binary clock like this with 20 LED's, if any one knows a place were I can get a schematic for building a clock that way it would be most helpful.
Thanks,
Kyle
