Hi.
In my Construction i need to know if this is the way to do it or ?
When IC4 goes high the output should activate all 3 transistors, and the LED's
When IC3 goes high the output should only activate the T2 and T3 and the LED's
and When IC2 goes high output should only activate T3 and LED's
Question is now,
How many diodes do i need ?
D1+D2 ?
D1+D2+D5+D6+D7 ?
D3+D4+D5+D6+D7 ?
D3+D4 ?
