Especially interested on how you are utilizing the hacker board. I couldn’t figure out how to implement it. Do you know if you can stack the hats? using the hacker?</p><p>I was going to use two raspberry pi ‘s. Then I have to share my logic over the network. That would make the logic more complex.</p><p>I’m new to all the circuit stuff. and I’m learning a real lot in this challenge&nbsp; and having fun doing it. . It’s an excellent learning tool...</p><p>I appreciate everyone helping me.</p><p>Steve K</p><img src="https://community.element14.com/aggbug?PostID=10246&AppID=269&AppType=Weblog&ContentType=0" width="1" height="1">
