Project with 4060 Counter IC
December 9, 2008
I can't understand why this project works as the guy states: http://www.kpsec.freeuk.com/projects/xmastree.htm
basically, by what i understood, the 3 columns of LEDs blink at different Hertz, but i don't understand why. Since they are connected to V+ and V0, should they stay firmly switched on? How can connecting a wire in between a column with an output which can be high or low affect this?
This is what i think can happen: when the outputs from the 4060 go low, they sink the current so the three LEDs of that column (at the top of the column) light up.
FIRST QUESTION: why does it get sunk by the 4060 (if that is what happens) instead of going directly the the negative pole of the battery? i suppose because there is less resistance that way?
When the outputs from the 4060 go high, erm...all the LEDs of that column light up? but then the LEDs on the lower part of the column would have more voltage right?
Thanks for helping :=)
