pin 3 & 9 will both be connected to the same 12V source, i think the reason why it says "directly" is that there is no problem with having a bigger voltage dropoff than 100mV
Does this work?
i added a resistor and a switch to the circuit of the datasheet... LM3915 (page 11, Pin9 internal circuit on page 9)
VCC 12V
V LED PWM 5V
while in dot mode
pin 9 is reverenced to LED9 minus 600mV and if below that threshold LED10 is switched off, this should work since the...
