Hello, I need to control about 144 switching transistors with arduino. What is the most convenient method to achieve that ? I still have confusion about multiplexing and shift-registers.. and I would like to have the fewest possible components around Thank you, Roberto

Your trying to control 144 things from a few pins hence using shift registers. What do you think multiplexing is? The term means many going into not out of one.
