Thanks Pauls,
I was declared a tempC like this on the begining:
volatile float tempC;
It was help.
As far as the buttons go, there is a LCDKeypad library for that shield that handles the buttons too.
For your menu, try the MENWIZ library
I actually have an additional question based on the LCD display for the arduino.
I want to have it set up to where you press two buttons at the same time and then continue in the if statement. But because the buttons are read with analog pins I am unsure as to what value I should make the conditional for two buttons, but only a single button. If anybody has any idea, please let me know!
If anybody has any idea, please let me know!
Write a sample sketch. Print the analogRead() value for one switch at a time, for two switches at a time, etc.
