im currently using the above schematic...
my question is how can i set the upper limit to light up all LED's @ ~8.4V
and set the lower limit to cut off all LED's @ ~6.0V
i think i will be ok with the 10k pot for the upper limit but the lower limit is confusing to me. now it has to reach 0V to turn off all led (pin 4 to ground)
am i correct that i would need a voltage divider and the VOUT goes to pin4 set at ~6.0V
since input is 12v i could use 2x 2.2kohm resistors (or any 2 of the same value)
is this correct or am i missing something else.
thanks guys
