I want to design some circuit which is drive 4 of led-diodes with npn, pnp, diode.
In my project our cpu has used most of its ports except only 2 ports.
And we have to control 4 LED with 2 ports
I want it operates separately in 4 conditions such as (High, Low),(H,H),(H,L),(L,H),(L,L)
I have some several Tr(npn, pnp) and resisters
How I solve this problem?
Help me.
