I had trouble getting the relays to work on the card then found that I had the One Wire chip, DS2408, soldered in upside down. After I carefully unsoldered each pin I put it down correctly and fired up the Arduino and was able to run the led strobe program which exercised each relay back and forth. Worked on getting my tower timer program working correctly. At first it seemed like the timer was not working but it really was the while loop handling in Arduino. Another issue was the check alarm. Couldn't get the return working. It turns out that I left out a return statement, I had only set the return value but did not send it back. I had to leave this momentarily because Libbie wanted to go out to dinner at La Cocina. We had the usual Quesadilla and a Margarita. When I came home I worked some more on the timer and had overwhelming success. The thing is ready to be packaged and deployed.
