    I apologize in advance as I am new to all of this and may not use the proper terminology or symbols. I recently purchased this LED Chaser sequencer. It has 8 channels. Everything is fine except that I can only really drive 1 LED per channel and my goal is to drive 8 LEDs per channel. From what I have been reading, I can use an NPN transistor, but I have no idea if I'm going in the right direction. So, I need help to very if the diagram I did is right. The attached diagram only shows 4 LEDs with 1 transistor, but I plan to do another identical and hook it up to the same channel. So 1 channel will be driving really 2 boards with 4 LED on each board.
