Hello,

I am creating a GUI to test machine equipment. The problem I need help with is when I click button 1, it disables button 2. Is there something I am missing? Thank you for your help!

I am trying to get my Arduino Uno to read multiple temperature sensors. I have it reading one and and outputting the time, but the second sensor keeps reading 0.00. The code is below. I have no idea why this is happening. I would appreciate any help. Thank you!
