Ah fair enough- I ll see what I can learn. Thanks again for your help!

I wasn't sure of the arduino current output so thanks for the input about the transistors. Also thank you for the code- I have 2 questions- First, what pin is the input or trigger to start the bullseye sequence? Second where it says "void loo" should that be "loop"?

Again thanks for your help I really appreciate it!

I am new to arduino boards but have a decent understanding of electronics. I have made a bullseye style light sequence using a plc but I want to try something newer than a keyence plc.

By bullseye sequence I mean I have 4 rings of leds. When a switch is activated it would start the sequence. So it would go (from the center out) 1-2-3-4 (with each light staying on as the next lights up.)  Repeat that pattern once- then flash all 4 ring together for a specified amount of time then turn off until the button is pressed again.

I figure I could just wire each output into a relay to control the led string since the outer rings draw alot of current.

I am not looking for the entire script to be made for me but a first or second step would be very helpful and appreciated.
