Resistors

[Vorex]

Would it be that bad to use a mix of 39 ohm 47 ohm and 51 ohm resistors for R1-9, R20-22. I only have 5 of each...and would really like to avoid a trip to ratshack...

47 and 51 are fine. 39 is 20% low, and will cause the LEDs to burn brighter and have a foreshortened lifetime.

Well..I just got it all together and flashed...it goes REALLY slow, just on the demo text...i ended up using 5 47's, 5 51's, and a 68...would this cause this or is it normal behavior...i don't think i can move my arm far enough to make it even say "minipov!" i see maybe 3 chars from that string =/

dont forget to burn the fuses! (look at the instructions again)

I did that, and it didn't make a difference...reducing the 10000 to 1000 seems to have fixed it wonderfully though!

Code: Select all

  OCR1A = (uint16_t)1000;

Now i'm going to see how hard it is to make this thing tell the time...
