Thanks, I will do that. At the moment they are not a problem, I am learning the use of different elements as I go. I have intergrated different skitches trying to find the problem with the run-away relays. The original sketch I used ran fine except when all relays where turned on, Then they would go wild. Faster and faster, until I shut them off or pulled the power.
I would like to know now, before the run-away problem, what is preventing the relay board getting signal. There is a signal going in on the Arduino-Uno board because I can see the TX light flashing when I press a button.
Thanks for the help.
