Not really getting how 24 mA output capability would be enough for the 240mA I need to lilt the row of LEDs?
Wouldn't a sourcing transistor array (is this a thing?) be the best solution? (incl ext power supply)
Okay but this would mean i'd scan column by column? if the anodes are connected to the rows and columns to the cathodes?
the resistor will then go on the anode* side of the matrix right?
