Slow Button/Switch Reaction

On my last project– which still isn’t done yet- the buttons for changing the temp display are very unresponsive.

The reason of course is because the Arduino has to loop through all the main code before getting around to checking the button status.

I found the cure! Interrupts!

EngBlaze has a great write up on how to use this. Whew! One less I have to write! Read it here. I’ll be modifying the Tri-Temp code to use interrupts soon. Sweet!
