Display disconnected, tried power from wall wart on two different Arduino UNO R3's with same results. While I am a newbie at this I have completed several projects, one using an LCD shield, lots of LED projects, one wire i2c temperature sensors and two wire i2c for LCD. Normally I can figure it out within a few hours using sample code or looking around the internet. This one has me stumped and I have three of these things to be used for pending projects.
Thanks for the help so far.
What next?
