Honestly i have searched for a thread that covered this....
I SWEAR i did....
And as much as i hate to ask you guys to read yet another thread w/ the words LED and 4017 in it..
So yea.. ive been through piles of threads here and across googlverse.
And none have fully covered my questions to my satisfaction..
So here it is, i want to use.
9 outputs, all 9 outputs have r/g bi color leds
All 9 outputs stay red until the output goes high at which time it goes green.
When the output returns low the led returns to red.
That is simple enough and covered in a few threads here and elsewhere..
Here is where im not so sure, i also want the same outputs to drive a relay..
So when the led is lit green the corresponding relay is closed, and when output goes low led goes red and relay opens.
All the methods ive seen of controlling the leds would make it hard to energize the relay coil.
Or perhaps im over complicating it and missing the obvious..not uncommon for me.
The relay(s) i have picked out are 5v 500 ohm coils, i had intended to just use these little TO-92 mosfets i have to drive the coils..
But that was before i decided i wanted some bi-color led bling ..
Thanks,
