Circuit schematic
Hi vne147,
the software I'm using is Proteus ISIS. If ISIS discovers a time problem I receive an error message, such at the one using the counter output pins without pulldown resistors.
I also tried using PNP-transistors on the high side, but there was one group of (activated) LEDs bright and all others were dim. That's not what I had on mind.
The problem is controlling a much higher voltage with low voltage (21V controlled by max. 12V, ignoring losses).
The circuit works fine with groups of three LEDs, and I guess we should "sell" it to the OP this way. Wiring will be very easy using my idea of 10-pin connectors.
To get the approximate number of LEDs, not 10X10X5 but 10X17X3 had to be used resulting in 510LEDs (LED spacing 1.96cm instead of 2cm for 10m length
) and one more counter IC. That one resets itself when counting to 7. (outputs 0 through 6 are used for the LEDS).
Schematic is attached.
