I have connected the second register in series. I haven't tested all of the LED yet as i had no idea of how to initialise the second register in code. Once i have had a play later on i will be able to see how it all works and try to add the additional code i need for two separate alternate flashing LED outsieof these chaser sequences! The whole circuit is for a model i am building so im hoping to get it going so that i can start the build. The ultimate aim is to run everything off an ATTiny85 which i think i can manage if i can keep the pin count down so wish me luck!
