dc42

Emitter to ground.
Base to 220 ohm resistor; other side of resistor to Arduino plane output pin.
Collector to cathodes of the 9 LEDs in the plane. The series resistors for the LEDs will be between the 9 anode lines and the corresponding Arduino outputs.
Formal verification of safety-critical software, software development, and electronic design and prototyping. See http://www.eschertech.com. Please do not ask for unpaid help via PM, use the forum.

perfect,
(each floor will have 12 LEDs in my project)

thanks, thanks, thanks very much
