Hi to all,
I have just built my second LED clock. The first was made from 5 x red LEds per segment and worked quite well.
I then decided to upscale the display and did exactly the same thing but using more gap between the LEDs and white superbright ones instead of red. Though I was still using the same voltage for 3 x white LEDs that I was using for 5 x red LEDs I adjusted the current to suit.
Now I find that the display is very flickery, really noticable! Also I have some odd segments partially lighting and I can only think it must be some sort of lag.
Does an LED turn on and off slower when given more or less current?
BTW the clock is driven by a PIC and runs at 1/4 display duty and there is no apparent flicker on the red clock or the strange "leakage" between segments.
Thanks, Al
